Multiple Mono Band 'Hertz' Center Fed Parallel Connected (MMBHCFPC)

Antenna System - Configuration Information (How it Works)

By Larry E. Gugle, RF Design, Manufacture, Test & Service Engineer (Retired)

A "Hertz" Antenna is an Antenna ½-wavelength long or any even or odd multiple of a ½-wavelength long. A "Multiple Mono Band 'Hertz' Center Fed Parallel Connected (MMBHCFPC) Antenna System" or a "Multiple Mono Band 'Dipole' Center Fed Parallel Connected (MMBDCFPC) Antenna System" is commonly referred to as a "Fan Dipole". This Dipole (D) Array Antenna System is Center Fed (CF) with 50-Ohm Coaxial Cable,and the Multiple Mono Band (MMB) individual Dipole wire legs are Parallel Connected (PC). The length of each separate individual Dipole is a ½-wavelength long on the band they are cut for,hence each Dipole presents a good impedance match to the Feed Line on the band for which it is intended to operate and a poor match on all the others.

As an example, consider a Fan Dipole consisting of a two band arrangement, with one Dipole cut to a ½-wavelength long on 75 meters and the other cut for ½-wavelength long on 40-meters. With this arrangement, a ½-wavelength Dipole bandwidth is obtained on both 75 and 40-meters, and in addition, the 40-meter Dipole is also a center-fed 3½-wavelength long radiator on 15-meters, which also presents a good match to coaxial feed lines. In practice, a good match results on 75, 40, and 15-meters. The 75 and 40-meter Dipoles are prepared for ½-wavelength long operation using the standard length formula (Length in Feet (L) = 468 / f MHz). Here is how the frequency selection occurs:

1. On 75-meters, the 75-meter Dipole behaves in the conventional manner, but the 40-meter Dipole is inactive because its terminal impedance at 75-meters is approximately 14- j1300 ohms. This impedance results in a mismatch of well over 2400:1 on 50-ohm line, assuring its inactivity. Consequently, this mismatch is sufficiently severe to result in an inactive 40-meter Dipole on 75-meters, especially since the 75-meter Dipole is taking practically all the power from the line because of its good match.

2. On 40-meters, the 40-meter Dipole behaves in the conventional manner, but the 75-meter Dipole is inactive because its terminal impedance at 40-meters is approximately 5000 ohms. This impedance results in a mismatch of well over 100:1 on 50-ohm line, assuring its inactivity. Consequently, this mismatch is sufficiently severe to result in an inactive 75-meter Dipole on 40-meters, especially since the 40-meter Dipole is taking practically all the power from the line because of its good match.

3. On 15-meters, the mismatch of the 75-meter Dipole is in the same ballpark as it is on 40-meters, assuring inactivity on this band.

4. If a 20-meter Dipole is added, there is a slight degradation in the impedance match of the 40-meter Dipole on 15-meters. This results from a reactance component in the 20-meter Dipole impedance when operating on 15-meters.

5. If a 10-meter Dipole is added, there should be no serious problem, except that it may require a little trimming to obtain a satisfactory match at a particular frequency in the band.

The bandwidth of each Dipole is practically identical with that of a mono band center fed Dipole, and hence, the stagger tuning arrangement provides a Multiple Mono Band Dipole Center Fed Parallel Connected Antenna System far more satisfactory than a Trap Dipole. Each Dipole in the center fed parallel combination may be supported from different directions if different directions of radiation are desired. Otherwise the shorter Dipoles may simply be suspended from the longer ones. Additional information on multi-band Dipoles in the stagger tuned parallel configuration may be found in the ARRL Antenna Book. _________________________________________________________________________________________________________________________________

Multiple Mono Band 'Hertz' Center Fed Parallel Connected (MMBHCFPC)

Antenna System - Construction Information (How it is Built)

By Larry E. Gugle K4RFE, RF Design, Manufacture, Test & Service Engineer (Retired)

It was learned from numerous personal installation experiences, over a 45 year Professional Two-Way - RF Communication-Electronics Career and a 53 year Hobby in the Amateur Radio Service, that both a ½-wavelength long "Mono Band 'Hertz' Center Fed (MBHCF) Antenna System", and a ½-wavelength long "Multiple Mono Band 'Hertz' Center Fed Parallel Connected (MMBHCFPC) Antenna System", mounted in Inverted-'V' configuration, work equally well. A "Hertz" Antenna is an Antenna ½-wavelength long or any even or odd multiple of a ½-wavelength long. The "Basic MBHCF"is commonly referred to as a "Basic Dipole" and the "MMBHCFPC" is commonly referred to as a "Fan Dipole".

The Antenna wire leg pairs can be positioned left and right of a center Balun or center Insulator on the support, in any configuration as long as the apex angle at the feed point and any bend in the wires is not less than 90 degrees. Any angle less than 90 degrees causes mutual coupling between the wires. The most convenient mounting height above earth ground for the center Balun or Insulator was found to be between 30 ~ 40 feet. End insulators are connected to the wire leg ends so that they can be tied off at either ground level or up to a 6 ~ 10-foot height above the ground level by the use of rope.

I use a 'Fan Dipole' mounted in Inverted-'V' configuration at my Amateur Radio Service Primary Licensed Fixed Station and it has six different pairs of legs connected to a W2DU design 1:1 current Balun on a 40 foot tall telescoping mast. The leg pairs are for the Medium Frequency (MF) 160 Meter Band and the High Frequency (HF) 75, 40, 20, 12 and 10 Meter Amateur Radio Service Bands. The assembled antenna has only 1 support (40 foot telescoping mast), 1 Balun (W2DU 1:1 current) and 1 Coaxial Cable RF feedline (100 feet of Belden 9913) and 12 end insulators (Ceramic Dog Bone Style) versus 6 supports, 6 Baluns and 6 Coaxial Cable RF feedlines and 12 end insulators. The entire Antenna System fits into my 80 feet wide by 52 feet deep fenced in back yard.

To have minimal headaches during theinstallation of a Fan Dipole mounted in Inverted – 'V' configuration do the following:

1. Cut the individual Dipole wire lengths for ½-wavelength long at the desired frequency of resonance using the standard formula (Length in Feet (L) = 468 / f MHz). Then cut the total length of the wire in half so that each leg is ¼-wavelength long. (Example for a 160 Meter Dipole for a frequency of 1.800 MHz the formula is: L = (468 / f MHz) / 2 = (468 / 1.800 MHz) / 2 = 260 feet / 2 = 130 feet long for each leg).

2. Mark all the individual wire leg pairs with the appropriate band number (Example; 160, 75, 40, 20, 12, 10 Meters etc.) and attach one wire leg from each band to each side of the center Balun or Insulator.

3. Connect the end insulators to all the individual wire legs so they can be tied off at either ground level or up to a 6 ~ 10 foot level.

4. Raise the Balun or Insulator to the desired height with all wires legs hanging freely straight down.

5. Start with the pair of wire legs cut for the lowest frequency first and stretch them out to the mounting level height, so that a suitable apex angle of not less than 90 degrees is obtained.

6. Adjust the pair of wire legs to obtain the lowest Standing Wave Ratio (SWR) possible on the RF Feedline at the 'single resonant frequency'' the legs were cut for. This indicates that the best impedance match has been obtained between the Antenna feedpoint impedance and the Coaxial Cable RF feedlines characteristic impedance. If a low-loss Coaxial Cable is used, an SWR of 3.0:1 on the feedline at the band edge is satisfactory. By using a Transmatch at the input end of the feedline at the station operating position, a proper impedance match for your 50 Ohm input and output designed impedance of any station equipment in-line before it can be obtained.

7. Once the first pair of wire legs are tuned, stretch the next lowest frequency pair of wire legs out and adjust them the same as the first pair.

8. Recheck the SWR of the first pair of wire legs and readjust if necessary.

9. Repeat steps 6 and 7 until all pairs of wire legs are done. (Example; if there are pairs of wire legs for the 160, 75, 40 and 20 Meters bands; start with the 160 Meter band wire legs first, then 75 Meter wire legs, then 40 Meter wire legs and last 20 Meter wire legs.

10. The individual wires do not have to be directly 180 degrees across from each other.

11. The individual wires can be bent or sloped to conform to the available space as long as any bend in the wire does not decrease to less than 90 degrees. (Example; the leg pairs can form the shape of the letters ‘S’ or ‘Z’).

12. The wire legs can form the letter ‘V’ laid down on its' side to shorten the overall length with the peak of the 'V' raised to the apex height.

13. The wire legs can form the letters 'M' or ‘W’ laid down on its' side to shorten the overall length with the peak of the 'M' or 'W' raised to the apex height.

14. The ends can be spaced evenly around in a circle to look like the ribs of an umbrella, or spokes of a wagon wheel. Also some ends could face East and West and the other ends can face North and South.

15. During Transmission and Reception the RF Alternating Current (RFAC) will follow the path of least impedance. This means the wire legs cut for the electrical resonance of the RFAC will appear as low impedance and the other wire legs will appear as high impedance.

Biography:

I was Born June 22, 1947, in the Country of Germany (Deutschland), State of Bavaria (Bayern), City of Munich (München), and given the name Erich Johann Von Richter. My biological parents raised my older brother Wilhelm Arthur Von Richter and I in Germany for the first 11 years of my life, however for legal reasons my brother and I were taken away from them in early 1958 and put up for adoption, because of severe child abuse (physical beatings).

In April of 1958 Dr. Lloyd James Gügle and Mrs. Eleanor Jean Gügle, of Ottumwa, Iowa, adopted my brother and I. We were moved to the United States after adoption and arrived June 15, 1958. I honored my foster parents by taking the name Larry Edward Gügle they wanted to give me. One week after arriving from Germany, I celebrated my 11th Birthday. In the German Public School system, I had completed, Kindergarten, 1st through the 4th grade Primary Education (Grundschule) and 5th grade Intermediate school (Realschule). Prior to the start of the 1958 to 1959 American Public School year, the Iowa Department of Education gave my brother and I an educational equivalency exam. Due to the results of the testing we both skipped one grade. We were assigned to Junior High (Middle) School; I was assigned to 7th grade (skipping 6^th grade) and my brother to 8th grade (skipping 7th grade).

On June 22, 1958 for an 11th birthday present, my foster father, had bought me a Hallicrafters Single Side Band (SSB) Receiver, Model SX-100 and a Superior Instruments Corporation Tube Tester, Model TV-12. Using my new SSB Receiver, I tuned the dial to different Radio Frequency (RF) bands, stopping often to listen to and especially enjoying the electrical and electronic technical conversations between Amateur Radio Service Operators. This sparked an extreme interest in understanding more about the Amateur Radio Service (ARS), and the field of Two-Way - Radio Frequency Communication-Electronics (TW-RFCE), so I told my foster father that I wanted to learn more about them.

In July of 1958 my foster father introduced me to our next-door neighbor Dr.Harper, who at the time of the introduction, was a medical patient of my fathers. Dr. Harper held a PhD Degree in both Physics and Electrical Engineering and had been a United States Marine Corps (USMC) Radio Operator during WWII. He also held an Federal Communications Commission (FCC), Amateur Radio Service (ARS), Primary Station License Grant (PSLG), Call Sign 'W0GK' in 1946 (His Original call was '9GK' in 1921, and 'W9GK' in 1928), with a Primary Operator License Grant (POLG), with Amateur Extra Class, Operator Privileges, a Federal Communications Commission (FCC), Commercial Radio Services (CRS), First Class Radiotelephone Operator License (P1) and a Federal Communications Commission (FCC), Commercial Radio Services (CRS), First Class Radiotelegraph Operator License (T1). He was employed as the City Radio Operator for Ottumwa, IA. He became my "Mentor" in both the Amateur Radio Service (ARS), and the Commercial Radio Services (CRS). I trained with Dr. Harper in Two-Way - RF Communication-Electronics (TW-RFCE), during my evenings, weekends, holidays, summer breaks from School, and time off from work for a total period of 11 years From July 1958 ~ June 1969.

In June of 1960 after finishing 7th grade from August 1958 ~ June 1959 and 8th grade from August 1959 ~ June 1960 of public school in Ottumwa, I wanted to give back to America what it had given me, which was "Freedom". So I decided that there was no better way then to serve my new country than in one of it's Armed Forces, so I could give back to all Americans. I started my military training, by attending High School as a full time Cadet, in the United States Army's Reserve Officer Training Corps (ROTC), at Missouri Military Academy (MMA), of Mexico, Missouri from August 1960 ~ June 1964.

In June of 1964 after graduation from MMA, Dr. Harper administered me the Federal Communications Commission (FCC), Amateur Radio Service (ARS), Novice Class Operators License examination. I received my Novice License in August 1964. I had applied for work at the local Radio and TV Repair Shop in Ottumwa and there was a requirement to have a Commercial Radio Services (CRS),,, Third Class Radiotelephone License or higher to work there, so in late June Dr. Harper drove me to the FCC Field office in Des Moines, IA, where I was administered the examinations for the FCC Commercial Radio Services (CRS),,, Third Class Radiotelephone Operator and Third Class Radiotelegraph Operator Licenses. I was hired by the Radio and TV Repair Shop as a RF Radio Technician and worked there from late June 1964 to mid June 1969.

My Amateur Radio Service Novice station consisted of a kit built Hallicrafters HT-40 Transmitter, my 1958 birthday present Hallicrafters SX-100 Receiver (disassembled and re-assembled like a kit), a homebrew Transmatch (two Air Variable Capacitors and one Roller Inductor from Military Surplus) and a homebrew Fan Dipole antenna.

In March ~ June of 1966 I home brewed a Two 572B Triode Electron Tube, RF Linear Power Amplifier, in Cathode Driven, Grounded Grid configuration, from instructions written in a W1ICP Lewis G. McCoy's 1966 February QST Magazine Article.

In April of 1969 my brother, who was home on leave (vacation) from the United States Marine Corps (USMC), suggested to me that if I wanted to continue with my ideal of giving back to America in one of its Armed Forces, that I should join the Marine Corps. I took my brother's advice and enlisted and started June 30, 1969.

I served on active duty in the Marine Corps from June 30, 1969 ~ June 30, 1991 for 22 years after which I requested transfer to the Fleet Marine Corps Reserve (FMCR). In June of 1991 I was transferred to the FMCR and served in the reserves for 8 years. After I transfered to the FMCR, I was employed in the RF Communication-Electronics Departments of 'RF Repairs & Service Company', 'World Communications Inc.', SanSys Inc.', 'Lucent Technologies Inc.' (during a joint venture with Philips Consumer Communications (PCC) Inc.), 'Motorola, Inc. Personal Communications Sector (PCS)' and 'Semiconductor Product Sector (SPS)'. While employed with these five companies I was the Senior RF Engineer (Sr. RFE) and Senior Program Manager (Sr. PM), supervising teams of RF Hardware, Industrial, Manufacturing, Mechanical, Service and Software Engineers. MyteamsDesigned, Manufactured, Tested and Serviced (DMTS) Commercial Consumer Products.
