I get Mil-grade RG-58a/u for $.23 per foot.  Not the Radio Shack crap.
This is traceable cable, 98% coverage tinned copper shield, 19 strand tinned
center conductor, poly dialectric.

You want cadillac cable...RG-142 teflon jacketed, dual braid, silver plated
cable is 1.75 per foot.  Super low loss.

Silver plated UHF for RG 58/142, teflon insulator, crimp on for 1.75 per.

SO-239 silver/teflon female connectors 2.00 each, panel mount.

BNC-M silver, gold pin for 58/142, crimp 1.75 each last I checked, depending
on price of gold.  Females are the same price.

Crimp tool and die for these sizes (both the bnc and uhf take the same die
size...) runs in the 75. range for both the handle and the die.  I have to
tool, by the by. Bought it when I worked in the avionics shop part time at
princeton airport back in the early 90s.

Shrink tubing is 2.50 for a 4' length of the 3/8" for the Alpha FIT brand to
cover the ferrule.  Use 1" per connector.  1 4' length will give you 24
ends, or 12 cable assemblies or thereabouts.

This enough to go on?
