Hi - I am a new subscriber to the list. I just put up a 3 el Steppir with the 40M option. I have had a problem with the boom rotating in the wind - the elements move out of vertical with a side wind
I don't think the jeep is too far off. We use a hydrostatic garden tractor. My wife usually drives and I am up the tower. If available we generally keep one person with their hand on the pull line at
I am sitting in the middle of our big midwest ice storm wondering if my new Steppir is going to succumb to the same fate as my Bencher Skyhawk during last year's ice storm. I just re-read Dave Leeson
" I don't recommend it. Regular RTV (room temperature vulcanizing) outgasses ascetic acid which is not recommended around electrical-type connections. You don't see any professional tower/antenna ins
Well, We had another good "blow" a couple of weeks ago and I found my 3 el Steppir/40 freely windmilling. I was able to rotate the antenna with the HamIV, but the brake no longer held for long. Lucki
Of Coure, just to balance the equation, in the big ice storm two years ago my Skyhawk broke its back (the boom broke) and my neighbor's TH7 came through unscathed. All in all I would rather have to c
I am a little behind on my email, so please excuse the late response to this thread. I have always left a little room - 1/2 to 1 inch between the rotator and the bottom of the mast. Obviously I suspe
Two items - 1) I just swapped a Yaesu 2800 for my HamIV in Rohn 25. There was plenty of space in the 25AG4 top section. This is the top section with no Z bracing in the top two cross braces. When I a
I am thinking of running two commonly fed inverted Vs, cut for CW and SSB to get coverage across the full 80 meter band. I should be able to space them at right angles. Has anyone tried this and if s
I have a HamIV which has low torque over part of its rotation. I have it on the bench and I can actually stall the motor by holding the top and bottom with my hands. The motor seems weakest over abou
Although I subscribe to documenting the wire colors - in the rotator's manual, I always cut a 6 foot pigtail and use molex connectors to join the two ends. That way I can quickly disconnect the rotat
Since I had a couple of responses on this I thought I would reply to the list. I get my molex connectors at Radio Shack. They are inexpensive and some have lasted for 20+ years for me. They are curre
I recently put up a Yaesu 1000 and used the same material I use to waterproof my outside coax connectors - a 3M #2228 rubber mastic tape. In the Yaesu case I taped the boot to rotator junction with S
"Hi Richard! As a rookie, I am always on the lookout to make this part of the hobby quicker, easier and more efficient. However, I've gone to the DX-Engineering site and [from your description] could

"Do you guys always lower the tower when you skip town for a day or two? Or go to work?" I can't speak for crank-up towers, I am partial to guyed ones, but I can tell you I disconnect all my feedline
As I write this I am looking at a cheap 90 degree adapter that caused me significant pain about a year ago. In the middle of a QRO contest I noticed the Alpha's output was becoming erratic. Great, I
