Loading coils for 160 meter antennas
WitrynaThe DX Engineering Vertical Antenna Matching Network, DXE-VMN-1, is a custom-designed impedance matching coil that is used at the feedpoint of a low band HF quarter-wave vertical or a Hustler 4-BTV, 5-BTV or 6-BTV multi-band vertical antenna. In most ground-mounted 160, 80, 60 or 40 meter mono-band vertical antenna … WitrynaAs I said, the load coil is a transformer, but it acts sort of like a dummy load. They take a tap from the coil through capacitance to feed the main element. There is only one exception, and that is on 160 meters. The CHA250B is not designed to cover 160M, so a tuner is necessary. See down below for more details about this antenna and 160 …

The main category is Antenna for 160 meters band that … Witryna31 gru 2024 · Assuming the antenna wire is ~3/8 wavelength at the bottom of 160M, and both coil and capacitor are variable (or switchable) then the antenna can serve well as an NVIS antenna across all of 160M and 80M. If there is enough interest, I could do a full post on building and using an Inverted-L as an NVIS antenna for 80/160 meters.
Witryna40 meter loaded dipole @ 41 feet long. $55.75. $14.50. Shortened 40 meter dipole shown with OPTIONAL "BL 10-160-5KW" Balun. Package price: Antenna with balun $101.70 + $13.75 S/H. WitrynaThe Square Section Top Band Loading Coil 160m Top Band End Fed Antenna -G3YEU Coil Details:- 5” (127mm) diameter using 16 SWG bare copper wire. Wound at 3.5 TPI ( 3.5 turn per 25mm) Number of turns depends on the length of the antenna. I used 3.5 TPI to make tapping easier and to keep the losses down, 11 turns were sufficient.
WitrynaThe antenna’s radiation resistance may well be below 5 ohms, and usually is. Therefore, most of the power goes into heating the coil and the ground system. To get the maximum radiated power, antenna current must be as high, both in amperes and elevation above ground, as possible. Loaded vertical antennas have a current maximum at the ground. WitrynaBasic Dipole Antenna for 160 meters. One of the major problems with a dipole on 160 meters is physical size. The formula 468/F will give the length for any given …
