Since twinax is shielded twisted pair, is a BALUN
necessary? For a while,
I used one twisted pair from about 50ft of ethernet CAT5 cable to connect
the S/34 in my garage to a terminal in the house. The connectors on each
end were two finish nails selected for the correct diameter. Worked fine
while I was play with it.
Twinax was a two-core coaxial cable...But it was so hugely expensive
(and hard to pass thru tubes) that almost all installations used BALUNs.
