Kelly and Roger,
Wonderful!
Plumbing is good!
Home Depot and Lowes are major radio antenna component suppliers in my
world!
Thanks!

No. The RF connectors would all be expensive and would eliminate the need
for couplings. The couplings I've seen used in hardline applications are all
hardware-store specials, designed for plumbing applications.
