[Elecraft] K2 - KAT2 Tuner and Alpha Delta DX-EE Dipole

Stan, 

I have one that's used for a general purpose (mostly 
for diversity receiving) antenna in my SO2R station.  
It works like what it is ... a fan dipole.

It's -extremely- well made and the over-all quality is 
top-notch, but it's -heavy-, requiring my 150# to pull it 
"tight", and it still sags a bit.  Mine is supported with 3/8" 
Dacron rope, and I wouldn't want to use anything smaller.  
I can't imagine the nylon cord supplied with it supporting
it .  

It does not cover 30M, but the tuners in the my K2 and 
K3 handle it OK.  The 80M loading coils are detuned 
when wet or snow-covered.  

It isn't a "nice looking" antenna, if that's important to you.  
The neighbors -will- see it.  The heavy, solid conductors 
need to be "fussed" with to even come close to being 
straight.  Like all fan dipoles, it will need several trips
up and down for adjusting the interacting adjustments. (:-)

I also have an 80M Zepp fed with  2"-spaced  #14 open 
wire line that works all bands very easily and is a -lot- 
simpler. It's been in place for 35 years. (:-)  It's fed via 
a 4:1 2KW HB balun.

Both the antennas are between towers at the 65' level.

Probably more than you wanted to know ....
