K2 - KAT2 Tuner and Alpha Delta DX-EE Dipole

I would like to correspond with a K2/KAT2 owner who is actually using an
Alpha-Delta DX-EE dipole. This is a rather pricey "limited-space" antenna and would like to hear directly from some "real world" users. My guess is that there won't be too many of you out there but I thought I'd ask anyway. My fundamental question: Does the KAT2 get along with the DX-EE on all bands? 73, Stan Levandowski WB2LQF HF QRP CW -- Doing more with less for over 50 years!

I have used an Alpha-Delta DX-DD for 40 and 80 at Field Day using a TS-480HX.
It worked very well on 40 but was tuned for the SSB band on 80 and we were working CW, so not so good on 80. I don't think the band was in good shape for 80 anyway. The quality of construction is very good in my opinion. The 40 performance is what you would expect from a 40 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 .... 73!

Ken and Brett, thanks for your responses. It's all helpful. I have to
think this through now. Thanks again, Stan Levandowski WB2LQF HF QRP CW -- Doing more with less for over 50 years!
