![]() You think it would be better to put it near the antenna instead? Lee, good info! I was thinking that I should put the 1:1 within a few feet of the radio to stop common mode currents from getting into the radio and also causing RF interference to my laptop, etc. On Tue, at 01:14 PM, David Lane, K4ZZR wrote: :-) -Leeįrom: On Behalf Of W4CW via groups.io Sent: Tuesday, Aug8:23 PM To: Subject: Re: Eagle One wire vertical Actually, you can almost never have "too many" choke baluns. That would keep the coupled shield from trying to supply RF current to your radio ground connection. Of course it wouldn't hurt to put one at the radio end too - in case there is still energy radiated (coupled) into the coax shield from the antenna (not likely if the coax is lying on the ground). Such a counterpoise, besides supplying it's own contribution to the radiation pattern, can develop high RF voltage at the radio end (resulting in "hot mic"). It keeps the coax shield from acting like a counterpoise "radial". ![]() A choke near the antenna will prevent conduction of RF current onto the outside of the coax shield.
