I really need to get one built for me, I don't have the gear or cable etc to make one. I did ages ago play about with a couple of lenghts of 1 5/8 heliax but it was a failure. Iam testing at present using 2 aerials it works but this is purely for tests. I don't mind paying a fair price 73 Steve ----- Original Message ----- From: "Matt Beasant" <[EMAIL PROTECTED]> To: <Repeater-Builder@yahoogroups.com> Sent: Saturday, March 18, 2006 5:37 PM Subject: Re: [Repeater-Builder] 6mtr duplexer > Hi Steve, > > The GB3FH repeater in Somerset is using a heliax duplexer and it is truly > excellent! > > If you like I can send you the plots from the analyser that shows the > performance of the duplexer, they are only small jpegs - don't think I can > send them to the list as I think it strips attachments..... > > Also, have a look at the web site www.gb3fh.org.uk for some photos from the > chap who made our duplexer - he made some mods that make it much easier to > tune and build.... > > Matt > G4RKY > GB3FH keeper > ----- Original Message ----- > From: "steve" <[EMAIL PROTECTED]> > To: <Repeater-Builder@yahoogroups.com> > Sent: Saturday, March 18, 2006 2:51 PM > Subject: Re: [Repeater-Builder] 6mtr duplexer > > > Hii > thanks for info, I will have another try, time permiting. > > 73 > > Steve > ----- Original Message ----- > From: "Robin Midgett" <[EMAIL PROTECTED]> > To: <Repeater-Builder@yahoogroups.com> > Sent: Saturday, March 18, 2006 1:19 PM > Subject: Re: [Repeater-Builder] 6mtr duplexer > > > > That's the same split (500 kc) as WB5WPA designed the heliax duplexer > > for....there shouldn't be any reason it won't work in the U.K. > > > > At 05:42 AM 3/18/2006, you wrote: > > >Hi > > > > > >yes Iam runmning 500Kc split 51.250 rx and 50.750 tx that is what the > > >powers that be in the UK issue > > > > > >73 > > > > > >Steve > > >----- Original Message ----- > > >From: "Neal Newman" <[EMAIL PROTECTED]> > > >To: <Repeater-Builder@yahoogroups.com> > > >Sent: Saturday, March 18, 2006 8:42 AM > > >Subject: Re: [Repeater-Builder] 6mtr duplexer > > > > > > > > > > The Heliax duplexer works great with a 1 mhz Split... but I think he > is > > > > Running a 500Khz split > > > > He will need either a higher Q type can Or more than 6 Heliax's > for > > > > the isolation > > > > > > > > > > > > Dick wrote: > > > > > > > > >Steve: > > > > > > > > > >A friend built one of trhese heliax 6 m duplexers and swears by it. > > > > > > > > > >73, > > > > > > > > > >Dick > > > > > > > > > >----- Original Message ----- > > > > >From: steve > > > > >To: Repeater-Builder@yahoogroups.com > > > > >Sent: 15 March, 2006 13:33 > > > > >Subject: [Repeater-Builder] 6mtr duplexer > > > > > > > > > > > > > > >Hi > > > > >can anyone recommend a cheapish 6mtr duplexer, not a home > > > > >made heliax one.
