WebMay 9, 2014 · Each radial came out to a length of 16.47 ft/5.02 meters. I had one remaining MFJ telescoping mast in the garage. The mast was 33-ft/10.05 meters fully extended. Since the length of the 5/8 wavelength vertical exceeded the length of the mast, I would run the required extra length to a nearby tree limb approximately 35-ft/10.67 meters above ground.

WebApr 5, 2024 · The antenna is sitting right outside my shack so the coax run is less than 20 feet. A quick retune of the coils, a bit of shortening on the ground radial, and I got an SWR of 1.8:1 at 1.915 Mhz. The antenna is under 3:1 SWR between 1.860-1.945 Mhz. The 160 meter band isn't that wide, so the tuner in the Elecraft K4D easily tunes up the antenna ... WebIn general, the taller the antenna, the more gain the antenna will have. So, if the bulk of your operation will be in town, close to the repeaters, a ¼-wave vertical should work well for you. If, however, you will be operating in fringe areas much of the time, then a ⅝-wave vertical antenna may be a better choice. A ½-wave vertical antenna ...

Thanks to Dan Vanevenhoven for these helpful guidelines on building a ground radial system for your vertical antenna. … meaning of dfiWebMay 28, 2024 · Radials are used to increase the conductivity of the ground surrounding a vertical antenna, to aid in returning current efficiently to the transmitter. Radials create a mirror-like reflection around the vertical antenna, which reflects radio waves that hit the ground off at an angle that simulates an "image antenna" beneath the surface, as ... peavey t-27 guitarWeb6. Rule of thumb: if the radials are elevated, at least two resonant radials for each band. If the radials are buried or lying on the surface, at least 16 radials, each at least a 1/4 wavelength at the lowest operating frequency, and don't worry about resonance: just get as much wire in the ground as you can.
