PVC conduit sounds like a good solution.
I'm delighted to hear the frequency divider board is performing good
service. I was rather surprised when there was insufficient interest to
justify getting a further batch of boards made up.
I'm pretty sure it would out-perform any micro based solution (no disrespect
to the TAPR board intended) in terms of jitter etc. especially if you used
thin film resistors instead of thick film in the clock circuit, but don't
have the test equipment to measure that.
I wonder if anyone did get round to measuring how good or bad it was - I did
try (with a lot of help from Bruce) to design it to minimise that sort of

I used a piece of pvc conduit to mount the antenna. It fits in the vic-100's
mounting skirt. If it does not have a mounting skirt, perhaps use a flange
and drill the appropriate holes, apply RTV (or your favorite sealant!).
(The divider board is working like a charm!! Even impressed the heck out of
my new GF!!! GEEEEKKKKKK!!!)
