To link a few sites you will do i little engineering.
1.) Will the site coverages overlap?
2.) How will the sites be interconnected? ( RF/Phone/Microwave)
3.) How much are you will to spend?
If the sites are going to overlap you will need to use different TX
frequencies or use VERY expensive high stability transmitters. If there is
enough separation between sites you could use the same tx frequency and
adjust the power to remove the overlap areas. Crossbanding ( is this a
word?) would be the least expensive way to link your sites together. What i
have seen is to feed the receivers back to a voter and send it back out to
the transmitters. Or crossband back to a hub site and crossband back to the
remote site transmitter ( I.E. VHF rx'r at remote site tied to UHF tx'r,
transmitting back to hub UHF repeater. The repeater output would be
recieved at the remote site and transmitted on VHF.) If you have
phone/microwave feed receivers back to voter and then send out to
transmitters. Again if you have overlap coverage then you will have to
operate on different TX frequencies so there is no same frequency overlap.
Hope this helps.
