WebI was trying to find a good multiband dipole to get me on as many bands as possible. I think for a multiband wire this is one of the best antennas out there. At 92 feet long and able to use it on 80M-6M its great! On 80M my SWR is about 5:1, but external tuner can match it up, 15M and 10M are a little high on SWR but tuner can make them work also. http://www.bvarc.org/pdf/g5rv_w5rh.pdf optical terms dictionary

WebDec 30, 2014 · The G5RV's whole purpose in life is to get the SWR low enough on several bands so that you don't burn up all your power in the COAX. For example, a standard G5RV has very high SWR on 30 and 17 and usually 10, and with long coax runs and/or small diameter coax, much, if not most, of your power goes into heating the coax!
