I was wondering if any one on the reflector has any comments about the pros and cons of putting rope in beam elements. It seems that the tips are always the first part of the beam to self eject. I tr

I have an XM520 assembled on the ground awaiting an opportunity to go up on the tower. It has a lot of sag in the boom without the truss attached. Too much sag, in my opinion, to put it in the air wi

With conventional yagi design, the element taper was gradual. The reasoning was that you make the elements stiff and strong. Since the element pieces were all 'about' the same size, they would self-r

Hawks have taken a liking to my Force-12 Magnum 340. Sitting on the boom doesn't worry me, but that's not the case with the elements. Would a plastic owl keep them off? Jim N7US With conventional yag

Plastic owls scare away what a real owl would scare away. Songbirds and hawks are not the natural prey of owls, so are unaffected. On the other hand, you won't have any trouble with mice or snakes on

Force 12s Tapering may have solved low wind speed resonances, However I have a broken shortest 10m Director on a C31XR-H which was rated at 135mph. That broke at the junction of the 5/8"and 1/2" tube

Not for long ! As soon as the hawks realize the plastic owl isn't moving (i.e. isn't living) they will reappear, just as the woodpeckers who liked the soft cedar panels of my house reappeared after f

Tom, sounds like a good dampening solution. Does the added weight of the rope contribute much to the "droop" in the element ends? -Paul, W9AC -- FAQ on WWW: http://www.contesting.com/FAQ/towertalk S

Guy, Please explain how a "sealed rope inside the element" wicks water when there is an END CAP sealing each element. I can see how an imperfectly sealed element may get water inside through condensa

What would be a suggested size rope to use on the Force 12 C31? Is 1/8" enough or do you need larger diameter? Will a solid nylon cord work (less wicking) to dampen or does it have to be real flimsy
