Jon, If they are that high, it is possible you assembled them incorrectly in order to fit around the diagonals -- just under the horizontal bar the bend in the guy brackets for the diagonal would be
I remember this tower from when I worked in Scottsbluff in the '70s. Was quite a thing to see. Here's a story from the Omaha paper and a couple of photos: http://www.omaha.com/index.php?u_np=0&u_pg=3
Jeff, You may wish to consider the type of tower. BX and HBX have no horizontal cross-members, making them very difficult to climb compared to something like Rohn 25. I have one BX tower, only becaus
There's a 140-ft (or so) self-supporting steel tower for sale locally. Was removed from service a year or so ago (replaced by a cell tower). About 4.5 feet across each face at the base; triangular; t
That one would scare the hell out of me! What I've done many times, using nylon or braided nylon, which has a bit of stretch to it, for the haul line, is to pull the section to where it is not quite
Hi Richard.... Yes, I have used this technique successfully. Mine had a 204BA at the top of the "regular" mast, at 80 feet, about 12 feet above the flat plate. I had a Wilson 4-el 15m yagi (17-ft boo
To: <towertalk@contesting.com> One advantage is you can climb easily (on the tower) to both antennas. No need to shinny up the mast to the top antenna. 73/Jon AA1K -- FAQ on WWW: http://www.contestin
Sounds like you have 3/4 inch 75 ohm CATV hardline. I've used more than 10,000 feet of it here and at my old QTH. Making connections is easy; you just need one double-female barrel connector and one
To: <towertalk@contesting.com> You could mount the plate where two sections meet, where there are no diagonals. If the rotor has a bottom mast mount, there is another solution. Make up a "T" bracket
I did this at a former QTH, where the control cable runs were 300-400 feet long. I mounted a 12.6 v, 3 amp center-tapped transformer on the rear of the control box. As I recall just half of the windi
Hi Ron.... If you are installing the starting capacitor at the rotor, i would recommend putting it OUTSIDE the rotor housing. This will simplify replacement so you don't have to pull the rotor out to
Hi... I came home from Dayton to find the reflector of my 204BA sagging from the first element joint (a few feet out from the boom). I recognized the problem immediately -- a few months ago the same
Herewith a summary of some of the replies on bolts and elements vibrating loose on my 204BA. Some great tips here, many thanx to all!...73/Jon AA1K "If you don't have time to do it right the first ti
I have a couple of boxes of Ideal brand hose clamps, labeled "all-stainless". But when I check the bolts with a magnet, they do show some magnetism. As I recall, there was a thread on here last year

Worth modeling to find out; I did this for my 204BA and Wilson 4-el. 15m yagi 6 years ago and found the patterns suffered at anything less than about 18 feet. Interesting trick! But I don't think the
OK game show contestants, here are your clues: 20-foot sections, triangular, bolt-together construction, galvanized. 19-inches on a face. The three vertical elements in each section are made of V-sha
Additional info: Weighed one 20-ft section today and it was 275 lbs. Thickness of the vertical "V" members is approximately 5/32". 73/Jon AA1K -- FAQ on WWW: http://www.contesting.com/towertalkfaq.ht
When I took down 100 feet of Rohn 25 this past winter at a friend's QTH, I opted to drop the 22-foot mast down into the tower and deal with it when all but the last two sections were removed. There w
