Rick I'm using 2 AlfaSpid's one in a Rohm 25 and one in a UST 89 foot crank up. They fit nicely in both. Julio, W4HY --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-boun
I've done 3 different batches of tower and have only had minor problems with the fit of the legs. The problems I had were fixed with a rat tail and a flat file. I think re-galvanizing is a much bette
They are number in my book. Julio, W4HY Hi. I'm looking for references for Hill Communications out of Bloomington, Ill. I'm considering buying my Rohn 55 sections and parts from them. Prices are the
Keith there was an article that appeared in QST in March of 1963 titled The Paul Bunyan Whip, with a subsequent article which appeared in a later issue. The article describes a 60 foot unguyed tilt-o
This is very simular to the one UST uses. With the exception that the mast diameter is 2 1/16" and has a 2 hole bolt pattern. I wonder if the 2" hole would be too small for some masts? Julio, W4HY to
I've had to do 3 re-cabling jobs. One a 72' UST where one of the cables was so bad it broke. One a 89' UST where the cables had more than surface rust and had more than the 6 strands broken rule of t
A friend and I were discussing his installation of a UST TX-455. I mentioned that it's a good idea to use a non-shrinking grout under the base. To which he replied that UST said that grouting isn't n
Didn't he write an article in Ham Radio Magazine about that? Does anyone remember what issue? Julio, W4HY I remember the magazine article where Wayne Overbeck ran around Southern California measuring
Funny thing about the Maxcom I think they are still being made and sold to the government. Julio, W4HY --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting
Be very careful about mounting a rotor between 2 straight sections if you have a problem with the rotor you will have to remove the antennas and mast to disassemble the tower to remove the rotor for
I have the 4 elem SteppIR with 2 passive 6M elems making it a 6 elem 6M beam. I also have a 7 elem M2 on a seprate tower. Using 2 6m rigs and using a local low power 6M beacon I see no difference on
The author of the LOGic8 logging software wrote a north centered driver for the AlfaSpid rotors at my request. Works just like a Hy-Gain under computer control. I have 2 AlfaSpids here and am very sa
Blake used my raising fixture from my US Tower to take down the tower in Orlando. We were able to get the UST fixture to fit the base attachment points on the HY-Gain tower base by using very long gr
Am I correct in my thinking that when you stack 2 antennas the E-plane beamwidth is halved. In my case I'm going to stack 2 VHF beams for 2M that have a 35 degree E-plan beamwidth I think it will be
I've located a piece of fiberglass tubing that I want to use for a cross boom on my V-UHF tower to mount a 1.2Gz loop yagi. The piece I've found is rather weathered and is frayed in several places on
I've used the jack system on both of my US towers for more that 15 years and it's worked well for me. I have had a slight problem with my HDX89 in that the grout under the base can cause a problem as
So far as I know only Black cable ties can be UV resistant. Julio, W4HY Don't take the UV resistance to the bank. I bought some blue tywraps that were allegedly UV resistant at a hamfest last year. I
On the other hand we used a hand manual crimping tool to re-cable a 106 foot motorized crank-up Tri-ex tower on a trailer and have experienced no problems. If the tool is made for the job I think it
No one that I know of and their parts are outrages. A friend of mine needed a new set of connectors one for the rotor and one for the control box. Yaesu charged over $70 plus shipping. I don't think
