OK, guess I have not spotted any recent ones! Will check the archives. ;-)

OK, here's a divergence -- I have these attached to the coax braid
about 25' from the rig. What will this do?

Part of my problem is that most, if not all, antenna theory books are
written about "perfect" antennas. My situation is such that I have
no trees on my property (thus the clothesline pole for support)
and am not near earth ground, AND my antenna exits a window down the hall
from the room I use for the shack. Unfortunately, I can't change that
anytime soon. So if I can make the rig happier (and possibly reduce
radiation
of the coax) with this bundle, I will be happy.

There's a market, I am sure, for a book about exactly how to make compromise
antennas and what parts of the system can have the most effect. 

Back to Elecraft topics: my luck with DX in this situation is proof that
the little K1 and its autotuner KAT1 is doing a nice job to get my signal
out into the ether. This discussion is not entirely off-topic, because
people considering portable K1/K2 ops may need to worry about not having
a perfect, resonant antenna to pack with them. 

Direct emails to me are welcome if people don't think it's fodder for the
List.

Thanks for the help!
