If an isolator is used between your TX & duplexer (always a good idea especially at comm sites; some site managers require their use), it doesn't matter what cable length you use. Bob NO6B Yahoo!

[Repeater-Builder] Re: repeater coax duplexer leads
Yes, Run what ever it takes to get from the radio to the duplexer. If the amp doesn't match the duplexer then build what some call a Z matcher it is a Pi network and consists of 2 veriable caps and 1 inductor. These things are way too simple to build to buy, and can be built for what you would pay for shipping for a commertial unit. Hent, look in most any ARRL Hand Book under low pass filters. The ones that I build for my repeaters usually costs me about 6 to 8 bucks each. 73 --- In Repeater-Builder@yahoogroups.com, Larry Kemper <[EMAIL PROTECTED]> wrote: > Anyone have any idea what length of coax I should run from the transmitter and receiver to the duplexer?

Double Mint, "two mints in one" My drawing of the DB-411-B has gone through a few revisions. I found another same model DB-411-B antenna in storage and have measured and recorded it's values. This second antenna was received complete, so it's measurements are more accurate. The $#%^# goof ball selling me the first DB-411 antenna (Ebay of course) cut off and discarded the lower half of the mast before he boxed and shipped it. ( wanted to string him up...) Notations are made for the estimated values of the first DB-411-B, but the second values included on the new paperwork will be of the an actual complete antenna.

Use quality coax (see Bob Dengler's message a few higher in the list) with silver plated connectors (no nickel) and start hooking things up. Folks use magic lengths to compensate for non-50-ohm environments, especially solid-state TXs, and to get the SWR under control. there was a thread on Z-matchers a while back I'd really like someone to consolidate all of that into an article for the archives at www.repeater-builder.com ...
