Michael:
I have a similar 2nd floor shack situation (see QRZ page K5AMH).
It's very possible to put a few feet or more of ladder line inside the
shack and loop it to save space. An antenna analyzer should show
you about how much feed line to add to solve the problem.
What kind of antenna

A method to approximate the appropriate add-on length is to use a
transmission line program, TL Details or ARRL's TLW.IF you know the
antenna feed Z and IF you know the feedline length in ft or w/l..then you
can use the TL
Hi all,
Thanks Josh, Rick, and Gary for the suggestions. It never occurred to me
to try to adjust the length of my ladder line.
I can't do too much heremy antenna mast is affixed to my house and my
shack is on the second floor. The ladder line comes off the feedpoint and
makes a nice arc
Michael:
Some have actually designed switches to put in
different lengths of ladder or window line, or
twin lead to adjust the impedance. I have even
used a large toroid at the TX with a few loops of
balanced line to choke out most common mode
currents in the feed line unless you want the
Hi all,
My last antenna experiment was a center-fed zepp cut for 80 meters.
(Dipole fed in the center with 450 ohm feed line, requiring a tuner.)
I found this antenna to be a decent multi-band antenna, with one exception:
I never could get my MFJ manual tuner to find a match on 40 meters. For
