[50mhz] 6 meter ant

One such HF antenna "matcher" did that 20 yrs ago....inside their "miracle"
box that was sealed was a 50ohm resistor!!!!! QST did an expose on it and
XRAYED the box to see the resistor and a 1:1 balun in it.....we had already
torn one apart at work weeks earlier ;)
SWR is NOT indicative of radiation efficiency....some folks tend to forget
that..
BTW the Dominator is NOT an antenna I would put high in the air compared to
a DB Products DB201 or similar.....the coil they use for matching will
likely blow up at the 1st lightning shot....AND the top is not a solid rod
but tubing with a white cap on it (can we say UV light????)...In a year or
so, it will probably have water filling the entire vertical length.....just
what you need for that KW amp to load into! (Or the rptr if you bought one
for that....they claim no one else builds a better ground plane...uh
huh.....lets see who is still in one piece after a year with storms
etc....In rptr service, the Dominator looks good on a roof top...but not on
a tower)
