Gentlemen:
I am trying to assist a friend from my local radio club in his efforts to
get his station on 160. He has a 43 foot vertical with 60 ground mounted
radials, and an AATU at the base. He sends DC on the coax to operate the
AATU.
I would think that it might be possible to add a horizontal wire at the
top, and switch in the
additional length to convert the vertical into an inverted L for 160, but
the specifics of how best to do this are not clear to me. I imagine a
vacuum relay would be the best method, but where should it be located, and
so on.
Rather than trying a number of possible things that might work (but not
very well), I am asking the experts on this list to provide the best
method, with specific instructions as to how to accomplish this, or provide
a reasonable alternative method that would produce successful results on
160.
I can furnish my friend's email for direct contact with him.
Many thanks in advance for your assistance.
73,
Fred W2AAB
