Just remember that solder does not survive contact with soil for very long. AM towers are connected to their radial fields in a similar manner. The ground ring is typically buried. But connections ar
I detest the prep and the inability of any Weller soldering gun I own to heat the barrel of the connector up to soldering temperature in my lifetime without melting the cable jacket. I've migrated to
I've spent some time going through the archives, but most of my searches tend to return 4 figures of results. If anyone could help me narrow that down, it would be appreciated. I'm preparing an appli
I've had a number of people respond to me personally. I assume those responses didn't make it to the reflector since they were only addressed to me, but maybe I'm just clueless on this whole email th
http://www.cushcraftamateur.com/pdffiles/X7.pdf The one dated 8/98 appears to be the current manual. At least, it has the address of MFJ on it and they acquired Cushcraft in 2009. MFJ is not noted fo
I'm no structural engineer, so perhaps someone else can bluntly point out what a stupid idea this is. What about filling the pipe with foam, the kind used in boat building? It's light and pretty stro
I've seen countless posts in various forums regarding the perforation of perfectly watertight pipe to aid "drainage". Do people get that much airflow through their buried and sealed pipe that condens
One thing any competent real estate attorney should be able to tell you is whether the restrictions are even enforceable. In the absence of an HOA (which are not common in my part of the country) dee
Braising is a way of slow cooking meat! I'll bet that translated into French wonderfully! Brazing is a method for joining metals. Technically, it's more like soldering than welding, as the base metal
soldering copper water plumbing. I believe the main reason for that is the worry of lead leaching into the water. Al AB2ZY Moisture is a big issue for standard lead-tin solder and over time it can d

I've never erected a guyed tower, but I was curious about the engineering behind that. The thermal coefficient of expansion of steel is 0.00000645 in/in/def F. Calculating for 115' of guy wires, I co
Waste of time. There are millions of miles of buried conduit in the world with no special care taken with respect to condensation. Unless you're planning to run uninsulated wire, I'm not sure what th

It's SABIC now. GE sold the Plastics business in 2007. The bulletproof Lexan was made by the Structured Products Group in Mt. Vernon IN, where the original Lexan resin plant was located. Al AB2ZY --O
FWIW, we've always had one of those invisible dog fences. The antenna system for those is basically a loop of insulated #14 AWG wire shoved into a slit in the lawn cut with an edger. Early in their l
Maybe it's the soil ph or something... I've taken to using black PVC water pipe. It's cheap and is almost as easily buried as coax. I jump on a flat bladed shovel to sink it full depth; yank the shov
I used 32' of fiberglass sections to support a K9AY loop, guyed in one place about 24 feet up. It's very sturdy once up and should be OK if sufficiently guyed, but I don't know how you'd stand 68' up
*Made to look like new*. Which reminds me, be careful at swaps. I've seen a lot of rotators for sale recently that look like new. Are they completely rebuilt, or have they just had a nice paint job?
Straying somewhat afield from the original topic... G0EVY has a full size 2 element 80m beam (think about that for a minute). I forget what he said it weighs, but somewhere north of 3000#. He bought
