Have recently rcvd a very old HF vertical antenna. It has
4 traps of
various lengths and overall lenth is about 30-33 feet
total. Cannot
figure out what brand it is. Donor has no clue. It also
has rings on
several separators for guy lines. I thought it was an
old Hygain, but
nothing in their current catalog looks like it. Best
guess is that
this antenna is about 35-40 yrs old and even wonder if
it's worth the
effort to try to assemble as it is in parts and there
were no
instructions. Found out from donor that it was only used
as a
listener, i.e. never was transmitted on... Making me even
more
suspicious of its reliability to use!
Any one with any ideas/thoughts---would be greatly
appreciated!!


Put it up and check it out you may luck out. If not remove
all the traps and put a tapped loading coil on the bottom
so you can tune it to your favorite band. I know of 1 guy
that had bad traps so he took them out rplacing them with
fiberglass rods. When he wants to change bands he tilts it
over and connects jumpers across the fiberglass sections.

Or, take out the traps, replace with conductive material
(tubing) and mount an autotuner at the base. Don't forget
the radials.
