... I have a assortment of antenna that I can use for listening .The one that I get the best Reception on is a 5/8 wave groundplane, feed with RG-59. I put my MFJ antena analszer on it and and the SWR was nearly flat all the way across (123 Mhz to 172 Mhz) this year I have things If you have an antenna with a swr that is flat over that large of a frequency range , you are loosing much of signal in the coax. You can probably take off the antenna and have about the same swr. If that is your best antenna, you have much work to do on all your antennas. Ralph, that was a pretty funny way of saying that RG-59 is suitable for 3' test leads only, never for transmission or receiving ;- 0 The differences realizable with RG-8U or 9913 would be amazing. For anything as high as high as 225-400mhz, hobbyists split hairs over a 1/2 db, and can never tolerate a 75ohm dummy load as a feedline. Down around 123 mhz, there would be slightly less difference. But a coat hanger fed with 9913 might do as well as a Yagi with RG-59! In order to operate during inclement weather, I had to add the losses from two connectors (with lightning arrestor) I didn't have when I used to disconnect and short to the ground bus. That had a noteable effect on vhf and uhf dx-reception. I have not tested dx-transmit since that installation. Jack Painter Virginia Beach, Va |
