Hello Tower Talkers,
I've decided to replace my TH-7DX with a larger antenna that includes 40M,
so I bought an OptiBeam OB17-4 and need to figure out a way to get it up on
the tower.
I was able to build the TH-7DX in my front yard in one piece and it was
then a simple job to tram-line it up to the top of the tower. The OB17-4 is
way too large to be completely built anywhere near the tower so I need to
figure out the best way to get it up there in pieces.
I have enough room to build the boom and the elements individually, but not
enough to assemble them to each other. For anyone not familiar with the
OB17-4, it has 17 elements on a 39' boom. The three 40M elements are 48'
long. The boom and each of the 40M elements has a truss to prevent sagging.
The tower is 60' free-standing with a 20' mast.
Anyone have any tips on how to make this work?
73,
Jerry
