I built the stubs up on an as-needed basis with whatever I had laying
about; there's no LMR400 around here. It's all RG-11 or 213. 213 has
a bit better attenuation dip and is more rugged. All of the T
connectors were Chinese specials initially and later most were swapped
with AMP parts that I ran across at swaps and hamfests. Never blew up
a Chinese one though so can't say the 50 year old AMP are better.
An excellent reply, Jeff. I wouldn't have gone to the trouble to write
mine if I'd seen yours first. :)
The only thing I disagree with is the use of the cheap Chinese tees.
When I got back on the air in 2004 after many years QRT, I bought a
bunch of those shiny cheap adapters so I would have them around. Over
the next 4-5 years (until I figured out they were all crap), they caused
me LOTS of problems that were a real pain to chase down --
intermittents, overheating, even adapters that fell apart! I had an
elbow overheat an hour into a contest -- the connection was a tiny
spring! A couple of runs to remotely located 6M and 2M antennas and
brick amps were intermittent -- they were a real PITA to chase through
the attic of my house in Chicago. Another went intermittent in a 10M
Yagi here in CA.
