Re: [TowerTalk] Quickly releasable knots/steering antennas duringtramming

["Mark ." <n1lo@hotmail.com>]

Hi All,
I have seen what you're looking for. They can be found by searching for 
"exploding knots".

They can be released by yanking the free end. You would tie the knot and 
leave the free end long enough to be taped near the center of the antenna 
boom, allowing the tower crew to yank and 'explode' them.

I have used a 3' tiller arm, clamped to the antenna boom at a right angle 
next to the mast mounting plate, and pointing away from the tower. A single 
tag line tied to the end of the tiller arm allows steerage left and right by 
having the tag person move in the appropriate direction.

If the tiller arm is clamped such that it is parallel to the ground, the tag 
man can also tilt the leading elements (of a yagi, say) up by pulling down 
on the tiller tag line.

For antennas larger than a F12 C3, you would want a longer tiller for more 
leverage.
