Please do the next time you see one using a thin wall steel mast with less than perfect plating that may quickly rust in some enviroments. So is Ameritron and their amps pretty much own the market. H
All of Rohns spacings are non interger for that reason but I doubt equal spacing would have much effect on a short tower. My 180' 45G is guyed at 40/80/120/160 primarily since it is at the section ju
Put the thrust bearing on a 45AG4 top section; the holes are already there for that purpose. Use a second bearing on a redrilled rotator shelf where the rotator would normally go and put the rotator
Dick is not built to stand up there! Gotcha Dick! When's the move? Carl KM1H _______________________________________________ _______________________________________________ TowerTalk mailing list Tow
Thats strange. Numerous YCCC and other serious contesters/DXers with big stacked arrays have been using dual bearings for decades with a significant reduction in rotator failures. Setting up a dual b
Use a short length of mast and let it all float until it is aligned perfect. The holes for the lower bearing should be slightly oversize for alignment. I use a digital level for that last tiny bit. I
I take it then that you have never experienced the installation of a large stacked array without a crane. Old wives tales? Hmmm, most of those that I know have at least a Masters degrees in an engine
Tailtwister with roughly 1/2 the weight of the array when dealing with a large stacked array and dual bearings. Hy-Gain doesnt specify maximum dead weight. Since very few would bother actually measu
Brake Clean if on the tower. Lacquer Thinner or Acetone on the ground. There are others but those are the most common. Carl KM1H _______________________________________________ ______________________
When there is insufficient meat to drill oversize, even to a metric size, then JB Weld or a similar hard epoxy can be used to fill the hole. Then drill and tap to the original size. Ive done this wit
Then wouldnt it be better to use a more permanent version as "long term"may be beyond the ability of 242 in an exposed enviroment? Im sure there are solvents that would soften a permanent seal if ne
Back in 1990-91, after moving to this QTH on a hilltop in the woods I started erecting the tower farm on 5 acres. As written I interpreted the regulations as not requiring a permit. The 60' tower at
Possibly aimed at its twin in Nashua, NH which is the FAA center for the Northeast. Carl KM1H _______________________________________________ _______________________________________________ TowerTalk
That is identical to the one at FAA Nashua, NH. Many hams work there and Ive been told that the logs have been deactivated years ago. The one here has a ham tribander above it. I was also told that s
The part about "assuming all guys remain intact" is the gotcha that any half awake local official will zero in on. Carl KM1H _______________________________________________ __________________________
That isnt so. A private grass strip has no FAA protection according to the guy I was talking to; it would be different if it was open to the public. They do have to register in order to be on a map
Jim, you are assuming brand new guy wire of the type defined by the tower manufacturer. Ive reguyed towers installed with wire rope and Rat Shack crap for TV masts. Dont expect the building inspecto

Amphenol outside, cheap ones indors has been my distribution. The cheap ones are more than sufficient for jumpers, feedline stubs, patch cables, etc. After awhile the savings add up and I havent had
With a 90' tower he can move the DE down and build a 3 el cloud warmer. A total of 65' is all thats needed. Carl KM1H _______________________________________________ _________________________________
