[TowerTalk] US Tower IV-16 Inverted V mount issues

[Alan Swinger]

I have one and stopped using it, even though I greased it and the mast,  due to the friction/pressure on the mast for the beam and extra load on the rotator. Have gone to a fixed steel crossmember to hold my 80M inv V.

I used that method on my last tower for years. Just need an extra hand to hold the ropes away from the tower face when raising or lowering the tower. But at least you can turn the antenna stack without the fear of tearing up the wire antennas.   Then, the next time I bring the tower horizontal, trash the darn IV-16.....
