Hi John,

I think a tee is an excellent antenna for DX and as others have mentioned
and that’s what I would us but thought I should mention something regarding
NVIS capabilities.  I suspect a tee is deaf as can be for NVIS signals just
like my 68 foot base loaded vertical that I use on 160 meters.  For
contests that involve working stations in very close (like within 150 miles
or so) there are times that I can’t hear the station on my TX vertical
whereas they are 20 dB or greater than my noise floor on my receive
pennants regardless of which pennant I select (really an amazing
phenomenon).

Just something to consider if you also need to work stations in close (like
adjacent states).

73,
Don (wd8dsb)
