You think the adapter loss is nutty, try different
kinds of good coax and rigid line to see that it
also changes things quite a bit.
For tight spots, consider superflex 1/4 or 3/8
in hard line. I actually use the mini 141 rigid
line for modest power levels.
Avoid trying to use foam center cables where
possible.
