The G7FEK 10-80m Garden Antenna. First off you have to know that I didnt invent this. As the heading suggest, it was designed by Mike, G7FEK. Its what some call a Nested Marconi antenna. The average HF Antenna uses elements that resonate on one primary frequency, and then at its multiples. For example the 20m Inverted V will work on. Search Hf Vertical Antenna No Radials. The problem areas were in the surrounding grounds, the radial system, and some lightning damage 5 MHz to 2 radials and vertical elements The HF Vertical Antenna Its Pros & Cons Wire antennas are a great simple way to work 40M and 80M rather than a noisy vertical antenna that requires horizontal radials Wire antennas are a great. vertical has a reasonable SWR on 60-10 meters, minimizing SWR-related cable- and unun-losses on these bands.However, this antenna is a poor performer on 160- and 80- meters due to the severe mismatch on these bands - bad enough that it is difficult to match from your shack if you use low loss coax. And even if you can match the antenna. Find HF Vertical Antennas and.

The basic parts for this antenna include a 20-ft6.097-m fiberglass pole, 35-ft10.67m of speaker wire, a portable power supply, a homemade cw key, and a camera tripod for mast support. At its simplest, the antenna is a vertical helix wrapped with 12 wavelength of wire for the chosen frequency. The other half of the antenna design is the radial system, which will initially consist of 32 16 radials, each about 40 feet Pseudocode Variables It is also possible to shorten them with marginal impact on the performance, especially if they are loaded to keep their electrical length MV10 Sandpiper HF vertical range antenna in MV7 variant 61015204080 and 160m Ground.

The calculators give you theoretical values, your actual construction will also affect the antenna greatly Basically lowering an HF antenna to about 120th wavelength above ground or lower, decreases the background noise level and distant station reception, however for this antenna design to fit within the desired space and keep the ends above pedestrian foot traffic using a.
