A few comments. I agree with all of Steve's comments also. 1. MA-550 is easy to raise and lower with the hand crank, but if you do it more than a few times a week, all the way up and down, it can get
I would also like to hear more about this, although I recall a thread on this matter a little while back. I've got my steppir at 65' and dipole at 75. I do worry about the derating, but keep it crank
Just a quick thanks to all of you that replied to my request for articles re: the NE power failure. I rec'd some very compelling articles, a number of which had not yet made it to the ARRL web site.
Ok, mathemeticians and engineers out theree.. I need some help Have an MA-550 55' tower. I have a little over 7 sqr feet of antenna. A Steppir (6sqr ft), a 40m D40 cushcraft dipole (1sqr ft) and a 2/
Curious how you arrived at a 25lb wind load. I'll clarify the situation, MA-550 55' (base): Steppir 6 sqr ft 10' + base D40 Dipole 1 sqr ft 20' + base Verticle+Mast 1 sqr ft does this still come up t
replying to the previous question, I forgot. The rotor is a HAM V (Tailtwister) at the base of the tower. I think that is more than adequate for the job, am I mistaken? K4IA@aol.com wrote:I am confus
hmmm, my PE calculations at 80mph give a max of around 6sq ft of antenna. Happy to show their calcs for MA-550 But to be sure, I'm putting in an electric winch to bring it down to "half mast" wheneve
after a few hours of busy signals finally got through and placed the order. I have found they are very hard to reach, but were very helpful. Thanks all for the feedback. MH Cqtestk4xs@aol.com wrote:I
I have the same issue with my MA-550 and the collar that hold the tube. Any ieas on where one can find this kind of teflon? I think it's a great idea. I saw a localham do something like this and it w
Hi all, Just a quick and hearty thanks to all who responded to my question about moving a tower. Your suggestions, ideas and photos were invaluable resource in planning this move. This last monday I
Ok guys, looking for some clever solutions. I just bought a tower, MA-550 with raising fixture and rotor base, sort of used. It's in Portland, I'm in Seattle (250 miles away). It was an opportunity I
I have had great success with Town of Bellevue, which is likely similar to MI in demographics. They yielded immediately to PRB-1 and even re-affirmed it in a letter they sent me recently in response
Cut off 10 foot sections of LMR-400 Ultraflex after putting up tower. I left them outside for two weeks during which time there was a heavy rain. I want to use the peices to make 3-5 foot patch cords

Dan, I was spoiled. I build an addition and had the contractor put 3" PVC into the house foundation and into the concrete tower base. I then dug a shallow ditch to the tower base. I use all gentle, s

On this same point, I do have a direct wire from an outside ground, through a wall connecting all my equipment. I use an MFJ antenna switch that grounds the antennas when I switch it off. How reliabl

don't most towers only attach by way of base plate? Most that I've seen you set the tower bolts in a wood frame and pour concrete around it. They need to be aligned well, but not perfectly plumb. the
Bob, How about bying a Steppir verticle (BigIR) and a second pole as a decoy and use it to suspect a clothes hanging line or something like that? The Steppir is built very inconspiciously and is hous
