The Rohn drawing shows the Rohn 45 sticking 2 inches into the bed of drainage gravel. If you are burying a tower section then the Rohn drawing doesn't require a rebar cage as the buried section of th
There was a case several years ago where an op was running a phone patch and the conversation switched from English to some other language. The op allowed the call to go on. It later turned out that
I found the digest difficult to work with. Now I have all towertalk messages go straight into it's own Inbox folder. I find that much easier to read and/or delete Mark _______________________________
Is it important that the guy anchors are out at the same distance?. For instance on a 100 foot tower. 45G Rohn says 80% which is 80 feet. If one guy anchor point is at 108 feet, one is at 97 feet and
I started to bolt some of my Rohn 45 together. Is there a torque setting for the tower leg bolts anywhere. How tight should they be? 73 Mark N1UK _______________________________________________ _____
The thing was that on Rohn 25 you get nowhere near the limits of the bolt before the tubing of the tower starts to crush. A small amount of crush is required without causing the tower leg to become p
I would just get another section of tower and put a shorter steel tube up there. I had a similar arrangement with my CL-33. The steel pipe will wear better I think. I would be concerned about the sof
. Here is his original post quote" I have 3 sections of 25G, the top being a 25AG2. I would like to use a 12' piece of 2" OD .25" wall 6061-T6 aluminum tubing to get a total height of around 40'. The
I am getting ready to pour the base for my Rohn 45 with a buried section. Is there any reason why I can't put a slope on the top of the base to make sure that water drains away from the tower legs qu
I am in the middle of installing a bracketed Rohn 45 with the bracket at 18 feet on the side of my house. Mark N1UK I plan to install one (45G) this summer bracketing it at 18' to my shop. I too woul
It is probably only about 4 inches thick or less....I can't imagine that it would provide the strength that you are looking for unless it was laid with mesh or rebar. Unlikely since most people are p
I notice that Texas Towers carries a line of steel masts. A friend recommended the 20 foot steel 0.25 mast. He said that if I nested about 7 feet or so in the tower and kept the rotor lower it would
Will the Orion 2800 rotator fit through the side rails of the Rohn 45 or do you need to cut/bend the rails. If it doesn't I might get the top base plate BPL45G and fit it to a standard section 10 foo
I poured the base for my Rohn 45 this morning. This tower is held upright with a wall bracket at 18 feet. How long should I leave the concrete to cure before starting work to add the next sections? 7
I am getting ready to install the grounding system on my tower. I imagine that I will be using Cadweld /ThermoWeld. I wonder if it wil be cost effective to use the single shot system rather than buyi
Yes I think that sounds like a great idea. I would look at brazing or cadwelding the connections between the expansion joints. Join them in several places so if one joint fails you will still be OK.
I have started my Rohn 45 tower projhect. I am planning to put a Cushcraft A3WS and a TH7DX atop this tower. I was planning on erecting a 100 foot tower but a fellow ham suggested that that might be
Thank you for all the good input. Here is a bit of additional information on my plans. Initially I was considering a 40m yagi but the wind loads scared me off , so now I am planning on putting a 40m
I am thinking of installing a tower climbing safety cable system on my Rohn 45 tower. Can anyone recommend a system for the Rohn 45. Will the Rohn R-TT10025 system fit a 45 tower. I see that the spec
I am looking at the guy anchors for my Rohn 45 tower. The Rohn catlaog calls out an AB2 hole which is a 6 foot long by 4 foot by 4 foot hole. The Rebar cage is made up from 10 #6 rebar rods held toge
