[Repeater-Builder] Re: Repeater /Crossband Help

Don, I will let Scott or Kevin confirm this but I think you are correct in that often times the transmit channel element is strapped to oscillate all of the time. Nothing wrong in doing this and it is not normally a problem unless you are very close to the repeater (usually within a few feet).

Re: [Repeater-Builder] Repeater /Crossband Help

Sounds like your channel element is "running all the time" You may need to force jumper your ptt to ground all the time and reconect your controllers ptt to the channel element select line so it only runs when it needs to. Other than that about the only thing you could do is place an attenuator

3” wide copper strap gives you 6” of surface area. ½” pipe gives you 1.57” surface area. So even 1” strap provides more surface area than ½ “ pipe. I think that you will find it less expensive than pipe and with the added benefit of not having to splice it every 10 feet. ¾” pipe gives you 2.3
