[Elecraft] The K2 and Random Antennas

[tom.w3qs]

Thanks for all the replies.  Leaves me with a lot of questions.  

My shack is located in the basement, and the only way to get RF out is by a
rather circuitous route through a couple of walls, so I don't think open
wire line is possible.  The antenna wire is then fed at the ground end.  If
I shorted braid-to-center at the rig and fed the whole thing as a wire I
have a problem with where to put the counterpoise.  I don't have room for
radials attached to the case of the rig, and don't have direct access to
earth-ground.

I gather mismatch at the feed point is the major concern, so do ya think
something like the par electronic end-fed 'dipole' would be better?

Bennie, any idea when the DLRDLL-EndFedZ will be available?

Tom

Tom ....

I would agree with Don!  The K2 & KAT2 should match it great ..... with or
without the radials.
When I was a young General in about 1959 or 60 I had great luck on 80 & 20
AM with a 60 - 65' longwire from the second floor window out to a tree.  The
shack was on the first floor with about 40 ft of coax of questionable
quality, and I used a tuner.  (WRL Globe Chief 90, homebrew cathode
modulator, WRL tuner and an SX-99 and a homebrew TR switch).  
The more OT's that told me it shouldn't work, especially with no ground, the
better it seemed to work!
Give it a try and be sure to report back when you put the K2 & KAT2 on it.
