[TowerTalk] Boom to Mast Fixture

[W3GCG@aol.com]

At W3GRF's, we used 70' of Rohn 25 for the boom of a 40 meter, 4 element yagi 
on a 100' windmill tower.  We had a steel plate, 1/4" thick, welded to the 
center of the tower and U-bolted it to a horizontal pipe which was U-bolted 
to a vertical plate on the mast.  It is called the PVRC mount so that you can 
tilt the boom over to attach the elements.  Balance is the key and ropes out 
from the ends that you can drop to the ground to pull the boom down or up on 
the PVRC mount.  Hope you can visualize the mount,  A picture would be worth 
a thousand words here. 73, Willy K3VW
