I haven't seen the original post on this, but if you are speaking of making an arc gap like commercial a.m. stations use (and some FM) there is more than just an arc gap. The gap is part of the over
Rain should just blow off. Ice or dirt should be more concern. I actually had to remove dead creatures from the gaps on our DA every so often. 73, Bill AI4WM _________________________________________
After spending most of my career working on commercial antenna products I have yet to find any amateur antenna products worth the cost especially if they are Cushcraft, Hustler, Hygain, MFJ, and seve

Sorry, I hit the return twice & it sent the first message. Re; the link. In any case it is very tragic when someone is killed doing their job. It is especially so when someone is doing what many of u
Interesting how a simple PL-259 can generate so much I need to add my 2 cents worth. I prefer the Amphenol connectors rather than others since they fit both RG-213, RG-8 and Belden 9914. I have used
Art, I would not go more than about 40 to 45 ft. with the fiberglass poles. Maybe use the aluminum equivalent if you go higher than that. The pole sections to which you refer are the 1080-01-179-6025

Yea, and they are straight line distance or air miles. I walked many of them...fun! 73, Bill AI4WM Cell sites are nothing. An AM array proof of performance has 20 radials, with 10 readings each... o
These make nice light shows at night other than that they do not work worth a hoot. Maybe at low power like 5 or 10 watts they'd work, but the inefficiency will eat up that small amount of power. 73
I have used thimbles and eye splices as well as thimbles inside of a small tightly tied bowline. The military uses thimbles with crimp ferrules to secure the rope. Whatever you use be sure the thim
These traps have caps on the end opposite the piston. IF the cap is good it will keep water out. The same for the heat shrink integrity for the piston end. The original heat shrink has a liner tha
One thing I forgot... When I installed my (bought it used) AP8A it would not resonate on 20M 30M was also off. I decided to check trap frequencies and found 17 off. I took this trap apart (even thou
Really sad when someone is killed participating in their hobby. My condolences to the remaining family members, neighbors and friends. I doubt those killed were hams, no names on the FCC database. Th
It all depends on what is available and when. Surplus sales are nothing like they used to be since the DMRO turned everything over to a private contractor back in the 90s. There are still limited l
Fence tubing is not seamless. It has a welded seam. DOM has nothing to do with being seamless only. If the tubing is extruded such as high quality aluminum it is seamless. There are exceptions to a
Jim, You've hit the nail on the head with all your emails. I have followed many (and more) of the same practices at several radio stations and except for a direct strike to the FM antenna one day (a
