Tnx Nate... If you can I'd shake the antenna while it is hot, while a weak signal is on the repeater input... that'll tell you real quick...as you probably know, dioding from anything loose really raises hell with repeaters... also dis-similar metals moving
Just to clarify... yes it is the VHF 210-C4 variety, the new ones made within the past 5 yrs or so that I am talking about... we have also had some trouble with the SRL2330 VHF duplexers, while the specs say 600khz you really have to struggle to get em and keep em there with any decent (-80db or better/side for the 6 can variety) rejection at a decent insertion loss -1.5db. Notch (reject) caps go seen to go bad prematurely, especially if you screw on em a few too many times. The "inside scoop" suggests that those duplexers should not be used at that close a spacing... so we went out and spent some serious coin and are now replacing everything with new Daniels and Comprod equipment.... getting tired of running up and down the hill every other day fixing junk that's long outlived it's natural lifespan.... that old service monitor/spectrum analyser I have is getting heavier by the day. 73 Richard VA7AA ----- Original Message ----- From: "Nate Duehr" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, May 24, 2006 3:04 PM Subject: Re: [Repeater-Builder] Sinclair Antennas > Richard wrote: > > <snip> > >> Anyone have experiences over the past few years?
