Has anyone who was on-site written up a concise and accurate description of what went wrong? I feel there is a valuable lesson to be learned. I've read tidbits but I don't think we've got the whole s
Good grief! How old is that catalog? From my days in the Coast Guard, I remember my CG manual showing how to use a serving tool but never actually saw one. It's used to form an "eye" in the end of wi
I looked in one of my old Rohn catalog and found the page. Not the same thing as I remembered from my seafaring days! What was the purpose in doing this if other than just looks? 73, Roger -- Remembe
There is a trap here waiting to bite the unwary. It's called ground resistance. Unless you have a very good ground system under the parasitic element you may not get enough current flow in the elemen
The contact material of relays plays a big part here. Contacts that are designed to switch microvolt level signals, do not handle power well. Conversely, power contacts can build up oxides which prev
I use a 12" piece of 2.5 in aluminum conduit as a joiner. I drill and tap for eyebolts for guys. OD is 2.875 and is a loose fit into 3" .050 wall irrigation tubing. 73, Roger ________________________

I put up 60ft of the Al masting by myself. It takes some time and you'll get plenty of exercise. You can probably walk up one third of the mast initially. I'm assuming that you will be using the inve
I disagree strongly! Lightning IS mainly RF and a good radial field is one of the better ways of dealing with it. Generally speaking, a good RF ground is a good lightning ground. A good 60 Hz safety
