Collin, Simply replace your existing harness that has 12" center-to-center lengths with an identical harness that has 14" center-to-center lengths. The two end pieces, the ones that connect to the receiver and transmitter, can be any length that fits. Please use RG-214/U double-shielded cable, in lieu of single-shielded RG-213/U cable. You won't regret it!
Since you mention eight pieces of coax, I wonder if perhaps you have the earlier version of the Q-202G duplexer. All of the Q-202G duplexers that I have converted had four cavities, and the cable harness comprised five tee connectors and two male N plugs for a total of six pieces of cable. Don't get wrapped up with wavelengths, because Sinclair wasn't that concerned about it; the high-split (150-174 MHz) harness had 12" spacing, and the low-split (138-150 MHz) harness had 14" spacing. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Sunday, February 24, 2008 4:39 PM To: [email protected] Subject: [Repeater-Builder] Help with Sinclair Q-202G Dear Friends, I am working on retuning a Sinclair Q-202G duplexer to 144.810/145.410. The question I have is about the new cables I will need. First will I need all new cables? What I mean is there are actually eight pieces in all. These need to be 1/4 wave each? Also when measuring these I know the measurement is from the center of the "T" connector. When measuring to a connection on a stub where is the measurement taken from? I have some RG-213 cables which measure 12" from "T" center to "T" center. Anyone that can help would be greatly appreciated. Thanks, Collin
