Although the G5RV is often promoted as an antenna that works well on all bands from 80 through 10 meters, that is absolutely NOT the case. To make a long story short: There are some bands where the SWR on the coax is out of sight and the feedline losses are astronomical. There is a better design, which involves shortening the antenna and lengthening the section of ladder line. G0GSF came up with a similar design that is a significant improvement over the G5RV. Even that design still doesn't cover all the HF bands, but it's certainly a worthwhile improvement. Before you buy or build that G5RV, do yourself a favor and Google ZS6BKW|G0GSF. This is not to say that the G5RV doesn't work well on SOME bands. But it does NOT work well on ALL HF bands. That's my point. http://www.karinya.net/g3txq/g5rv/ See the note at the end http://www.nonstopsystems.com/radio/G5RV-1.pdf See Part 3 at the end! http://www.nonstopsystems.com/radio/ZS6BKW.pdf http://www.nonstopsystems.com/radio/ZS6BKW-2.pdf http://www.nonstopsystems.com/radio/ZS6BKW-3.pdf http://www.w8ji.com/g5rv_facts.htm It works great on 75 meters!
