Fact or Fiction

[grape ape]

I found this MATCHER SWR TUNER. Is this a fictional device or does it work? I know there are tuns of gimmicks around especially in the CB world since they have been around a long time.

will ONLY work.....with an antenna that has a gamma match....ie: capacitor

IN short Yes they work. Antenna matchers work on a simple principle of impedance matching. See your radio is designed for 50ohm out, the coax is 50ohm, and ideally your antenna should have a 50ohm load thus giving you a perfect match(swr 1-1) Now if your antenna is tuned for 11 meter and say you want to use 10 meter your antenna system would have a mismatch. All the antenna matcher does when you turn the knob is make the radio think that it is seeing a 50ohm load (it would actually be something like 54 ohm or whatever). The antenna is still out of tune but the radio would think that it is in tune.

Thank you...
I now understand. Once again this is the best CB sight on the web.
