I use my middle name, 'LEE', but my first name, 'LARRY', is okay too.

To check out my 30M/40M wire beam antenna experimental data or information about my murder mystery novels go to my website: www.lleewatkinsinfo.com or Amazon.com & enter L. Lee Watkins

QSL Policy: I do not collect QSL cards, but will gladly send a card if requested. No postage required--just ask.

SHACK PHOTOGRAPH: 1000 Gallon homebrew automated planted Amazonian aquarium. Control/monitor panel in far corner; control electronics in cabinet below. 

Transceiver: Kenwood TS590S;  Amplifier: Ameritron AL-80B  Antennas: 5 band 2 element Quad up 17M (20-10M); 3 Element Inverted-Vee Wire Beam up 14M (40M)

45' push-up fiberglass masts to support 3 EL Beam

Experimental Antenna Notes: I have modeled, built and tested the following fixed beam configurations:

2 element and 3 element 30M and 40M Delta Loop Arrays with relay switching to select directivity. These beams work well given the 30M loop is only 17' feet above ground and the 40M loop is only 10' above ground. However, there is a lot of interaction between elements and tuning is difficult.

2 element and 3 element 30M and 40M  Inverted-V wire beams (120 degree apex angle). This design is for separate 30M and 40M elements, with 30M elements approximately 12" below 40M elements--some interaction between the sets of elements, but relatively easy to tune.  This antenna generates big signals.

Note:  I have removed the NW and SE masts, leaving NE and SW directions which simplifies the installation and makes tuning much easier!!
