I recently wondered the same thing about a Phelps Dodge six cavity duplexer
here. I found that all six cables including the two to the tee connector
were the same length: 8-3/4 inches tip to tip on PL-259 connectors.

The problem here was noise, lots of it,

The only problem with the coaxes you mention is that the braid is not solid
or silver-plated. If any water

RG-400 is indeed double shielded. BUT, that brown transparent
coax I have looks like RG-400 and has an mil std number stamped on it, but is
single shielded. The tag attached to the coil says RG-400.
It's in the trash can
Neal,
The best answer to your question is probably: Whatever works! Both Bill
Lieske of EMR and Len Pringle of Telewave have given me pretty much the
same answer about jumper lengths for duplexers they manufacture.
In most duplexers, the cavities are individually tuned for the desired
Interesting! emphasize double shielding and recommending RG214.
RG-223 is double shielded, it isn't recommended. Why. RG-142 and
RG-400 are single shielded and are considered qualified. Hm

Interesting I would have thought that also... However one of the

This is why I am confused about the type cable..
BTW the WP-641 is a 4 cavity 8" Can Duplexer...

Some well known manufacturers did use RG-213 and RG-8
for duplexer interconnecting cables. Some people
upgraded the cables to double shielded coax, but you
have to take velocity factor into consideration when
making the new cables.

Wacom referred to 'their' RG-213, as "Modified RG-213", which was
actually RG-214, and was truly double

Neil,
OK, here is the scoop on the interconnecting cables. I just measured a
Wacom 641 factory manufactured for 146.445/147.445. All the cables are exactly
12.75 inches long PL connector tip to tip. Both Rx and Tx sides, and going to
combiner Tee antenna connector are all the same length.
Thank You James..
