I had problems keeping a Diamond tribander on the top of my mast, it was simply too flimsy to survive 100' above the tree line on my exposed hilltop. Solution was to side mount upside down and loose
Very true! I do a fair amount of MIG welding and the wire has a short spool life if left inside an unprotected garage. I can imagine instant rust outside. Carl KM1H __________________________________

A good choice for toroidal baluns as well as VHF/UHF 1/2 wave baluns is expanded PTFE (ePTFE) since it is very flexible and does not exhibit the center conductor flow of solid dielectric. It also exh
The ePTFE that I mentioned earlier is the Gore development. Regular PTFE was around much longer. I got the whole history lesson some years ago from a good friend who was the regional manager of the G
Does anyone know the dimensional size of the angle iron used in that bracket? Im going to be building two of them next week and there is a pretty big difference in cost of 1 1/2" thru 2" angle stock.
Anybody know of any sources in this area that the EPA and envirowhackos havent shut down? Ive some small items such as brackets and angle iron to get done. Carl KM1H _________________________________
I remember that several years ago an alternative theory was making the rounds for tower protection. Its basis was to have the tower as the least likely target for the leaders. By having an insulated
The HAM series all clunk when the brake is activated or released. The sound is transmitted thru the tower. I can hear my Tailtwister 100' away and 100' up. ___________________________________________
Is it a complete crank up or just sections. Rohn did not make a crank up. If it is a crank up what is the actual height when extended and how long is each section? Im a bit confused as to what you ac
Well it is probably not a Rohn tower. Rohn 25G is 12", 35G is 15" and 45G is 18". It could be an antique KTV from the 60's which Rohn bought and discontinued that size; the smaller KTV became Rohn 6
Measure the voltage at the rotator and go from there. I seriesed a 10A 10V filament xfmr with the brake line on a 250' long run and it worked fine. The motor itself draws much lower current. Carl KM1

My wife doesnt give me grief when I use the 22. However she got a tad upset when I blew a chipmunk into the next county with my Dirty Harry S&W model 69 44 Magnum. She also sort of went ballistic whe

Then I suggest that you and others who like to make believe that you are scientists form your own metric oriented forum. I KNOW how to convert when I have to but I have absolutely no intention of doi
The ham band designations are a long established convention that we all follow. Metrics are not taught in school and my kids used to ask me what I was talking about. The US almost went completely met
Burial is becoming as outmoded as ham radio. Both will be history before many of you are dead. But this is getting a bit off topic. Carl KM1H Well this entire problem will come to pass when all the o
