Paula, Some missed points are the weight load and mast length. Your tower is rated for a top load of approximately 150 lb.s on a 2 foot mast. Either antenna, rotor, and a short mast will bring you ve
________________________________ Mike, The perceived weight at the winch (with a single pulley) will be far greater than the weight of the tower because of the shallow angle of the layover cable when
The type motor needed is called a wash-down motor. Leeson is one such manufacturer. That is what my used LM-470 had on it. No problems with rain water incursion. 73, Jim W5QM ________________________
John, If you have utility easements that you plan to place your guy anchors in, you need to research whether or not it is allowable or safe. 73 es gl, Jim W5QM ________________________________ _____
John, I would consider both of these tower sections to be good candidates for the base section to be buried in concrete. Personally, I wouldn't use them anywhere else. I cannot recall a bent diagonal
John, My experience was with a Triex LM-470 and a Tennadyne T-12 lpda antenna. While it's not the same weight or exposure it did enlighten me to one drawback of a crankup. Tower sections clanked as t
No arguments from me on the value of QSL cards. I too would rather have a card than an LotW confirmation and do for all but one of my confirmed countries. My point was just that for ARRL awards, LotW
Mike, Look for a boot with a heel that will keep your foot from sliding off a tower rung or step. Also, look for one that has a steel shank imbedded in the sole. That will provide more support for yo
What are typical values for the capacitor and the MOV in a control line and /or rotor line shunting type surge supressor? My control lines are running 12v DC at maybe .3A max and the rotors are Hygai
Jerry, First off, welcome to the hobby! Tashjian Towers is what became of Triex. Their web address is www.tashtowers.com. You should be able to get everything you need from Karl Tashjian, be it engin
I can only imagine how wallowed out the bolt holes must be on a self supporting 40' Rohn 25G tower. I won't climb more than 20' of unguyed 25G. The "I've done it for years" statement is not an accep
Charlie, Tnx for the Youtube link. I'm curious how far the noise propagates down the mains as in, how far away of a neighbor might be the source of the problem. I have already ruled out my own lamps
Fastenal, www.fastenal.com is a good source for anchor bolts. You can either go to your local store or order online. Online has the stock while the stores may be hit and miss. As for a homebrew basep
Alex, PVC pipe in no shape or form will work for your intended purpose. You couldn't guy it enough to make it stable and it is prone to breakage right at the diameter change of a glued joint. Militar
Check McMaster- Carr. They list them but with a higher price tag. The manufacturer you want to search is Martin Sprocket and Gear. Any supplier of power transmission equipment ought to carry them. If
Eric, My previous house had a 12/12 pitch roof- 45* and I used what we called a chicken plank. It was a long 2x4 with rungs made of short (3 1/2") 2x4s nailed to the longer one every foot or so for f
Larry, You are correct but let me point out a few qualifiers. The base for a self supporting 45G tower specifies a huge amount of concrete (5' 3" x 5' 3" x 48" deep or 4.1 cubic yards) and the load o
It's cheap insurance to replace the guy and you won't be second guessing yourself down the road. Both heat and moisture are enemies of the core material in Phillystran. My other concern would be the
Greetings, Does anyone have a good source for tower or vertical base insulators? Used or surplus is ideal for a commercial type insulator. Larger diameter fiberglass rod (3'' or better) is another id
One vertical is made of 3 and 4" aluminum tubing. It is 1/4 wave on 80m. The other plan is for a 1/4 wave on 160, made of either Rohn 25 or 45, preferably the latter. I like the old Lapp style tower
