Re: [Repeater-Builder] VHF Splitter
The most common method of using one receive antenna with multiple receivers is a multicoupler. This device usually has some sort of preselector followed by a preamplifier feeding a two-, four-, or eight-way splitter. The gain of the amplifier is selected to just overcome the losses in the preselector and splitter. I assume that your packet digipeater has separate TX and RX connections, so that it won't transmit back into the multicoupler. 73, Eric Lemmon WB6FLY drwoolweaver wrote: > Ham club wishes to use one VHF receive antenna for three different VHF > receive systems.

Re: [Repeater-Builder] VHF Splitter
Be careful ! Won't the packet digi also transmit on the same antenna line ? Thereby destroying the other receivers ?? -- Original message -- > At 06:01 PM 7/23/2005, drwoolweaver wrote: > >Ham club wishes to use one VHF receive antenna for three different VHF > >receive systems.

I do this at home, with nothing more than a radio shack 1 in , four out TV amplifier, with FM trap. Basically, you'll need a wilkinson divider, which is what a TV splitter is. Mini-circuits sells precision 50 ohm types. If you need, amplification and filtering can be done either before the splitter, if all the frequencies are close enough, or after the splitter with more narrow filters. Yahoo!

[Repeater-Builder] VHF Splitter
Ham club wishes to use one VHF receive antenna for three different VHF receive systems. Two VHF repeaters and one packet digit. Any suggestions on how this can be done and where is the best place in the antenna system to install a preamp? Transmitters are combined and use separate antenna. Yahoo!
