I am trying to salvage the situation before going to
war with Antennas and More with my credit card company. They shipped the
wrong antenna to me and have NOT answered numerous calls or emails. I was
looking for a 40 meter OCF dipole and they sent me a 80 meter OCF, which
was not what I ordered because of space limitations.
If I could cut the thing down to use on 40 meters then I can save the
inevitable hassle of dealing with this outfit and going to war with them via
my credit card company.. However, my understanding is that a lot of the
commercial builders of the OCF dipoles use a 2/1 balun for their 40 meter
antennas since they are trying to match a different impedance spot on the
shorter antenna., hence it is not necessarily the case that you can just cut
them down. Any thoughts?

ware of is the problems with getting basic information about the antenna
from the "manufacturer." What I have is a 132 foot off center fed

dipole
they refer to as the Windom HSQ. What I am trying to decipher is what
type of balun they are using. In their literature they refer to a 1 to

1.
This can not be. From the location of their balun which is about 48

feet
from one end, I am guessing that they are trying for the illusive 200

ohm
impedance point for 80 meters and that the balun may be a 2:1. This
company does NOT return any calls. I was trying to figure if I could cut
this antenna down to a 40 meter version, which might be possible with a

2:1
balun, but not a 4:1. Anyone have any experience with this type of
antenna?


The balun is probably a 4:1 and the antenna should work pretty well on
40m with an antenna tuner without any cutting. Borrow an MFJ-259B and
see where it is resonant.
