Listening to all your restrictions, Alexandre, I would try to get access to two towers at least a couple of kilometers (5-10km would be even better) apart and put in a 1.2m or 70cm link between them. Put the receiver on one tower and the transmitter at the other (best if sited on hilltops or tall buildings). If you have a preferred direction of coverage (ideally at a right angle to the line between the towers) you can use yagis for tx and rx pointed parallel and that plus the distance may well cover you. If you cannot get duplexers and don't want to do cross-band (all new radios), then the BIG separation is the cheap way to go. You can use yagis on the 1.2m link between the towers. -- Dave Gomberg, San Francisco NE5EE gomberg1 at wcf dot com All addresses, phones, etc. at http://www.wcf.com/ham/info.html -----------------------------------------------------------------
