Multiband wire antennas and ATUspop
- DC1YB experience on multiband wire antennas. In particular examine FD4 windom and G5RV antenna, considering noise levels and matching aspects.
Author reviews also the usage of Automatic antenna tuners in TS-50 TS-480 and GC-3000
JA7KPI Windom antenna for 40-80
- The total length of this antenna is 41m, height is about 11m, and diameter of element is 2mm.
JA7KPI modified this antenna originally used as Inverted-V type of 80m band Dipole.
Works on 40 - 80 meters band with acceptable swr.
Feeding an End-Fed Antennapop
- End-Fed antennas are NOT balanced systems; but neither are verticals, ground planes, discones, windoms, zepps, Marconis, half-slopers, et al. Additionally, the low-impedance antenna port of your transmitter/receiver is not balanced.
The FD4 (FD3) Windom Antennapop
- The 4-band Fritzel model FD4 is a special version of a Windom antenna. It is a half-wave long on the lowest frequency, and is fed from a coax cable through a transformer inserted in the wire at one-third from one end
Comparison of two windom antennas
- The antenna comparison being reported was between a commercial Chelcom 136ft multi-band windom designed for 80m to 10m and a home brew 260ft full size windom designed for 160m to 10m by G0VVN, G3KAU and G3GRO
Windom for 80-40-20-10 m
- A windom multiband antenna for 80 40 20 and 10 meters band. Include picture for a 1:6 Balun. In french
Windom Antenna with 4:1 balun
- The Windom is an Off-center wire multiband Antenna. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers .
HB9Z Internet Remote Base
- A controllable TS2000 made available at HB9Z in switzerland. Antennas are Carolina Windom 160 for 160-10m, a 5-Element Beam for 20-15-10m a
G5RV for 80-10m and a V2000-Vertical for 6m, 2m, 70 cm.
