Eric:
Thank you for taking the time to do this. I will make the cable lengths 14" as measured center to center on the T connectors. I will use MIL spec 214. I found crimp rings at the RF connection. (Just in case you might need some one day) 73 Gregg _____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Lemmon Sent: Tuesday, March 25, 2008 12:23 AM To: [email protected] Subject: RE: [Repeater-Builder] RE: Sinclair Q202 duplexer harness info Gregg, The Sinclair cable harness for the low-split Q202G duplexer should look like this: <-----[]-----[]-----[]-----[]-----[]-----> TX 1 2 ANT 3 4 RX The "[]" symbol is a tee connector. The distance between 1 and 2, 2 and ANT, ANT and 3, and 3 and 4 should be about 14 inches measured from the center of the back of each tee. The distance between TX and 1, and between 4 and RX, can be whatever length it takes to fit without any excess or splices. The 14 inch dimension is based upon using RG-214/U double-shielded coax. I got these dimensions by measuring a brand-new harness that a local club purchased from Sinclair. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com [mailto:Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com] On Behalf Of Gregg W6IZT Sent: Sunday, March 23, 2008 11:15 AM To: 'Gregg W6IZT'; Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com Subject: [Repeater-Builder] RE: Sinclair Q202 duplexer harness info -----Original Message----- From: Gregg W6IZT [mailto:[EMAIL PROTECTED] <mailto:w6izt%40bellsouth.net> net <mailto:w6izt%40bellsouth.net> ] Sent: Sunday, March 23, 2008 2:06 PM To: 'Repeater-Builder@ <mailto:%27Repeater-Builder%40yahoogroups.com> yahoogroups.com <mailto:%27Repeater-Builder%40yahoogroups.com> ' Subject: Sinclair Q202 duplexer harness info Our club has what we believe is a Sinclair Q202 duplexer. This variant has piston trimmers to adjust the notch frequency. The coax harness is beginning to fail (the braid is fraying at the crimp on a couple of the cables). I do not know what frequency this duplexer was originally tunes to. What I need is the proper length of the cables that make up the harness assembly for operation in the 2 meter band. If you know the physical dimensions please include the cable type and/or velocity factor Hopefully someone Thanks Gregg W6IZT
