Am I radiating almost everything the radio is putting out? Or could I still be having big losses in the tuner? How can I test it? Put the forward/reflected power meter on the output of the tuner. Then calculate the losses in the feedline. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 80,000 Newsgroups - 16 Different Servers! =----- |

Losses could certainly be in the balun. The coax terminators on the tuner do not use the balun. A separate SWR meter will have coax terminators, requiring the use of a standalone 4:1 balun after the meter, into the twinlead. This will test tuner losses, but not losses in the balun. I guess my follow-up question is, How do I test for forward/reflected power in a twinlead feedline? I have an RF probe; can that be used somehow?
