Peter, I haven't seen this mentioned, but perhaps you could do a split-site repeater, with a 2m rcvr, basic controller, low-power UHF transmitter and small solar panel ready to hang on a utility pole somewhere, then park the SUV with a UHF link receiver and 2m transmitter a half-mile away but line-of-site.
More pieces, a little tougher to set up, but much more compact than using a 2m duplexer. It's hard to beat 440 for a mobile or portable repeater. Tiny duplexers work, surplus commercial gear is cheap and plentiful, and many hams have radios for it. The repeater part is easy on 900 MHz and 1.2 GHz, but almost nobody has radios for those bands outside a couple big cities. 73, Paul, AE4KR ----- Original Message ----- From: Peter Dakota Summerhawk To: [email protected] Sent: Wednesday, October 07, 2009 5:15 PM Subject: [Repeater-Builder] Question on portable repeaters Morning, We are looking at building a portable repeater for special even use. This will be mobile mounted and 2M. My questions is this: If we are using two radios (one for TX one for RX) then what does the antenna separation have to be for all of this to work? Planning on mounting this in a SUV so roof space can be adjusted if need be. Thanks Peter Dakota Summerhawk Laramie County ARES
