#Antenna guy wire portable
(VHF and upper HF.) With an alligator clip to your transmitter it can become a portable quarter wave monopole. Lowest frequency (maximum length) indicated is 17 mc. It then shows where to cut the quarter wavelength wire for that freq. Measure from the dipole center, pull it out stopping at the frequency you are using. Here is a cool 1950’s tape measure for field antenna work. Write this equation inside your helmet: L = 468/f Where L = end-to-end length of the dipole in FEET, f = operating freq in MEGACYCLES. I have used the types of parts and techniques in this kit for 50+ years and it supports almost any kind of field (or home) radio installation from HF through 6 and 2 meters.
Included is my experience-driven rationale for what is in this kit and what is not, and why.ĭescribed below is my kit as it fits in a standard US Military M-1956 “Butt Pack”.
No “Rocket Surgery” here, just proven, simple, efficient systems that work very well in a field environment. I’m not into chasing long distance “DX” very much but any of these horizontal wire antennas will work over very long ranges especially when elevated to around a half wavelength.Ī simple kit for temporary, lightweight, deployable wire antennas is essential for any field Ops. My focus is on regional comms with my family, my buddies and EMCOMM groups on the Low HF bands and local comms on VHF. The employment of these antennas is generally for my portable field Ops, typically camping or otherwise vacation/road trips.
The Question: What do you want your portable field antenna to DO? Antennas can have high gain, high bandwidth or small size.
