I have built a single line tram to lower my TH6DXX from 60 feet and raise a new
Force-12 C3E/D. The tram consists of a 4 foot length of 1 1/2 inch PVC pipe.
Across one end I attached a 3 foot piece angle iron using a muffler clamp at a
right angel to the pipe. Also, I used some angle iron (it is the stuff you use
to install garage doors) from the from the tips of the 3 foot piece to the back
of the PVC Pipe. The PVC pipe acts as a tiller...while the cross piece of
angle iron acts as a seat to the boom of the antenna.
The troubling part of this is the single line. I've seen double line tram
systems but I just don't have the room to do that. City lot stuff. So, using
a single tram the issue is that the antenna could roll if it out of balance.
Obviously, balance is very important here.
What I did is used a piece of rope connected under the cross arm tha carries
the boom up and hung some wieght below the tram to keep it balanced. The more
weight ...the more stable it should be ... but that comes at a cost. The
weight is fixed on the rope to keep the whole tram in balance....but that
doesn't mean I can sloppily put the boom on the tram without taking into
account balancing the antenna.
The whole mess has to go up to the tower and will travel less than 150 feet.
What have others done here to "balance" an antenna while using a single line
tram?

In our day and age it seems that Common Sense is in short supply. If you don't
have any Common Sense - get some Common Sense and use it. If you can't find
any Common Sense, ask for help from somebody who has some Common Sense. Is
Common Sense devine?
