WebHomebrew G5RV All Bander. The G5RV is an easy-to-build 80-10 dipole requiring no traps. All bands are covered, including 30, 17, and 12. The G5RV has high SWR, by design, on most bands and a tuner is required. Unlike most dipoles, the “basic” design is not a 1/2 wave, but instead a 3/2 wave dipole on 20 meters.

WebUse an old AM radio and look for switching power supplies and wall warts in your house. Problem is the whole shebang is an antenna with that setup - move the tuner to the feedpoint of the antenna (at the ladder line), put a choke on the coax at the tuner and then run the coax back to your rig. Should help a lot. WebHigh SWR Troubleshooting Guide. In this guide, we walk you through the process of troubleshooting SWR issues. Starting with the most common occurring SWR …

A simple DPDT knife switch (or banana plugs and jacks) near ground level lets us use 75/80 and 15 meters, if desired. Even though the VSWR is relatively high on 75 and 80 meters, lower coax loss on that band at least lets us operate there using just one multiband antenna. NOTE: The remaining 8.5′ section is not … See more Although the popular G5RV antenna is often promoted as an antenna that works well on all bands from 80 through 10 meters, that is … See more Depending on which bands you want to operate, there is a better design which involves shortening the antenna and lengthening the … See more Our modification to the G5RV and ZS6BKW antennas, while also somewhat of a compromise of frequency ranges and VSWR, lets us use all HF bands between 80 and 10 except 30 and 60* meters.

The problem is that at VHF the effort is less effective and more prone to failure. I happen to have tried both dipole and an double extended zepp (basis for G5RV) and the Zepp does perform better IF the feed system doesn't have high losses. govt bed college in bhopalWeb2. A G5RV antenna is a dipole with an impedance-matching ladder-line feed stub, with the dimensions of the wire and the ladder line carefully chosen to provide a low SWR on many bands. (Please note that there are bands where G5RVs and variants perform terribly.
