gin with the MP -33 settings and then set the 20 meter section; and last, the 40 meter section. A package Of anti-corrosion compound is included and should be applied to all telescoping element sections as per in- structions on package. When assembly is completed, apply antenna coat to parts of antenna except plastic parts. How to improve fish tank filter
What is the most compact 40 meter antenna that you'd consider using for QRP? Discussion in 'General Technical Questions and Answers' started by KB8NHL, Apr 5, 2009. The Bird Cage Antenna was designed by Dick Bird, G4ZU (SK). It is basically a folded X-Beam, and very compact. This was the very first wire beam that I ever built. I got mine to work, at least a little bit, but I could not keep it working. The material I used was too flemsy and it kept collapsing.
I didn't even bother to measure it but just loosely wrapped about 6" from each end around itself. It's only about 10' off the ground at the moment and my built-in automatic antenna tuner has no problem getting from 1.0 - 1.5: 1 on 80-10 meters, even though it's built for 30-40 meters. I'm waiting on an antenna analyzer I ordered to fine tune it. ground plane antenna with radials . By John Portune W6NBC . I wanted high efficiency 40 Meter antenna with low-angle radiation. My inverted-V at 40 ft. performs well, but is “a cloud burner,” good for local contacts within 500 miles. A vertical seemed the obvious answer, a naturally low-angle radiator.

Tuning the COM-40VA 40 Meter Vertical Antenna is straightforward and intuitive. If you use an SWR meter or an analyzer at the base of the antenna you will get the most accurate readings in a timely fashion. Since the 2:1 SWR bandwidth of the antenna is wide the adjustment parameters are relatively broad and fine adjustment is not usually necessary.

To make a small adjustment to the sky-loop as after some storms it is resonant at the bottom of the 40, 20 & 15m bands and when I operate higher in the band, I need to manually adjust the ATU to match the impedance at high power (the 10w auto tuning signal is OK but 300w+ isn’t and means I have to manually tune (match) the antenna).
