Hi all, The repeater antenna will be on 7/8ths hard line which is already installed.
I am also looking at how we might be able to put a yagi lower down, but it needs some height because the repeater we're linking to is about 80 miles away. The LMR-400 was meant to be for the link radio only, not for the whole repeater. I'm not apposed to using half inch hard line either if it'll fit. I need to do some more investigating but thanks for all the ideas so far. This is a great opportunity because it'll double my repeater's coverage area. Thanks and 73, Chris, KG0BP ----- Original Message ----- From: "skipp025" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, November 04, 2004 7:13 PM Subject: [Repeater-Builder] Re: combining a UHF link radio and a UHF repeater on one antenna > > > Hi Chris, > > Sure you can do both transmitters at the same > time using a hybrid tx combiner panel and a > matching combo notch pass receiver preselector. > > Not a lot of hams do this type of setup, but it's > done all the time at commercial sites. > > The fly in the soup is an instant half power lost > from each transmitter via the hybrid network. > > You can also close space combine with very high Q > cavities (and a lot of them), but it will be touch > and go and possibly not work well. > > I'd throw the LMR-400 idea away and use actual > hardline.
