Ham Member Lookups: 13206


This is my hobby as I retired from the workforce in 1995 as a professional engineer in mechanical. I was licensed as a novice around 1957 as KN4RVN. I am a real amateur radio operator, not a pro like some of you. LOL. I served four years in the US Navy from 1951-1955 with 3 years and 4 months aboard the USS Carter Hall LSD-3.

My antennas are a 5 band Hex Beam at about 50 ft using a modified hazer and a Rohn 25 40 ft tower with a 12ft mast, and a homebrew 40 meter bent dipole beam at 50 ft on a 16 ft boom using quad spreaders and a ham 2 to rotate it. I have a Ten Tec Omni 6 plus and an Ameritron AL 80A amp . I recently bought a  TenTec Omni 6 with factory option 3 upgrade plus an AL 80 B amp to use on 40 meters.  I  built the two element 40 meter bent dipole beam. It has a driven element, a 16 ft boom and a director. Looks from a distance like a cubical quad.  It is on a 50 ft rohn 25 tower with a 10 ft mast and a hazer.  I have relocated my shack from the basement to my spare bedroom room in the house. The 40 meter beam is 175 ft of coax from my shack now.

This next photo is my 40 meter bent dipole beam on a quad frame. The wire of the driven element is 66 ft long fed at the top horizonal with an insulator but horiz. is only 18 ft long. A 16 ft boom places another wire 62 ft long as a director on 40 meters. This is a full 1/2 wave length 2 element bent dipole beam. Also loads great on 15 meters and good on 17 meters.  I run 850 watts usually . Signals sent are normally 59 plus in the states and even some DX. It is rotated with a Ham 2. I added my first ever tuner for the beam and it operates the entire 40 meter band with no reflected power now. This photo shows the center insulator, center feed coax, and a homebrew coax choke on a ferrous form attached to the spreader near the boom.

The director is just wire attached to the spreaders in the same configuration. Works great

for a pile of junk.

I have made some changes since the photo. I removed the balun. I now use a hairpin match to step up the low impedence balanced antenna to 50 ohm unbalanced coax. Works great, made from # 12 wire. The vertical wires on the sides now drop straight down in lieu of bending back toward the boom. I now run 900 to 1000 watts depending on the frequency. Great signal reports,also hears well.
