Interestingly I was in with a group that understood the importance of
good feed line and good antenna's. Never did hop up a set and that's
what actually channeled me into amateur radio.
One of the fellows in the group was an EE - actually designed a tube
based 1KW amp for the 11m band. Now if he'd gotten his amateur ticket
and moved it up to the 10m band he would have been pretty much legal.
