Steve, That trick works fine for offsetting the harness tee from the loop assembly in the can, but it doesn't do a thing for increasing the spacing between the tees. The later-design Sinclair Q202-G duplexers come with a one-piece harness that is made up from sections of RG-214/U cable with five crimped-on N tees and two crimped-on straight N plugs. The tees are made by Delta Electronics, and are intended for one-time, permanent installation. Even if great care is used in cutting off the ferrules, it is very easy to damage the tee during the process.
Although it is time-consuming to dismantle the high-split harness and re-build it with longer cable sections between the tees, the club chose to buy the harness from Sinclair. It cost about $125 five years ago. Once the new harness was installed, the Q202-G duplexer tuned up perfectly in the 2m band. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Steve S.

This adds about an inch without having to rebuild the harness, or else a nice way to test cable lengths. Also if adding the elbow makes things worse, then you might want to cut and try. 73, Steve NU5D Eric Lemmon wrote: > Bill, > > This topic has been addressed several times in recent years.
