Doc,

Thanks very much for you detailed HL Ant comments. I hope mine will do as
good a job for me as it has for you!

Hope we meet on the air in the future.

Should have the K2 operational on a longwire in 2-3 weeks. Then when the
snow melts I will work on getting the loop up. I found a source for a 9:1
balun that should work matching the unbalanced coax from the shack to the
side of the house where I plan to use about 40-50 feet of  450 ohm ladder
line to feed the loop.

From reading all the reflector messages, I see that the Elecraft community
of operators are very a very talented, creative and helpful group.

73s,

Jack
