You probably are going to put more stress on the tower by adding the additional weight and wind load of the extra parts Vs. cutting the brace. In other words... Cut the brace. 73 Jim W7RY A while bac

How high was the SWR? What the defective connector at a high voltage point? A high current point? 600 watts on SSB or CW is pretty low duty cycle. I run 1500 watts on RTTY contesting. I have NEVER ha
There should not be any heat in the first place with 600 watts on SSB or CW. 7/16 are a good connector, but an overkill for MOST amateur installations. They are a superior connector to the type N, bu
Gas tubes for 5, 6 and 11 GHz? I bet the microwave down-coverts at the back of the dish and your running 1/2 LDF down the tower. I've never seen a lightning surge suppressor on a piece of waveguide a
That's going to leave a mark! Get well soon! 73 Jim W7RY Please Excuse the one handed typing. Lowering the AV640 via winch, the wind was pushing the mast over about a foot too far to lign up with the

Dont run the ground wire in conduit. Run it in the ground... Works better that way ;) Keep the ground wire at least 24 inches from other conductors. Ground radials with rods are a great way to go. Ke

Ill try to send out a link to download it tomorrow. You need to register, so we (Motorola Solutions) can send out updates and keep track of who has it. There is no cost. Thanks 73 Jim W7RY Hi Jim, Th
