RE: [Repeater-Builder] Decibel DB-4076 duplexers
There were a number or revisions to the DB-4076 over the years - here are at least 4 different cable lengths/sets depending on the vintage that I'm aware of. There is no magic formula. --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of James Adkins Sent: Sunday, November 16, 2008 6:08 PM To: repeater-builder Subject: [Repeater-Builder] Decibel DB-4076 duplexers I just got a set of Decibel DB-4076 duplexers, currently tuned to 452.xxx and 457.xxx Mhz.

RE: [Repeater-Builder] Decibel DB-4076 duplexers
James, The length of the cavity interconnecting cables is dictated by the frequencies to be duplexed. If you intend to retune and use your duplexer in the 70cm Amateur band, the interconnecting cables will be longer than the original cables, and if you want to use it for GMRS, they will be shorter. Be aware that the correct lengths of the cables will take into account the lengths of the coupling loops that are hidden inside each cavity, so the cables themselves are not going to be an exact fraction of a wavelength. Decibel Products duplexers are now sold and serviced by db Spectra. For technical support on cable lengths, contact them here: www.dbspectra.com/WebSite/ContactUs.aspx 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of James Adkins Sent: Sunday, November 16, 2008 3:08 PM To: repeater-builder Subject: [Repeater-Builder] Decibel DB-4076 duplexers I just got a set of Decibel DB-4076 duplexers, currently tuned to 452.xxx and 457.xxx Mhz.

Re: [Repeater-Builder] Decibel DB-4076 duplexers
I did send an e-mail off to DB Spectra tech support. The duplexers have N-females on them, and from what I found on the repeater builder website, it was a smaller style of coax. We'll see what they have to say and I'll pass it along in case someone else needs the information later down the road. . .
