The 4 connected directly to the cavities are 10.5" (cable end-end). The other 2 are 11.5". The cables to the Ant "T" are 13" & 14". After trial and error I get the RX and TX down to 1.3dB ea. The

RG142 and RG400 mentioned by the OP is most certainly double shielded and silver plated. Kevin W3KKC

* I recently purchased a set of these cavities in the cabinet. There are rather different versions of the Q202 – those with dielectric-tuned capacitors and those with piston trimmer capacitors. The

Aloha from Down Under.. Not being sure which cap is installed in this duplexer, I wonder if these rather cute lil things might do the trick. I obtained a few some 10 years ago through a South
