elements made from the .065 wall aluminum don't seem to exhibit this tendency. A little thicker than the normal .058 (the stuff that costs 4 times as much) and designing them to have a bit of droop -

I did just that on a 5 el 40m yagi that I built a couple of years ago. The boom is 60 feet of square aluminum tower and I wanted to not only reduce the torque effects but to have some way of making s

Either your option 1 or 3 would work fine, I'm sure. Number 2 is likely to end up with an inverted Vee scenario, as you suspect. 3 might be a bit quicker, but involves more work on the tower. I'd per

The vibrating plow attachment found on many trenchers is ideal for situations where you don't need an open trench. The plow attachment on (for example, one I know well) DitchWitch 4010 is about 1" wi
I do have some data on the L&R towers (I have several LR20 towers up as well). It's a pretty solid tower (20" face) that can handle a lot when guyed properly. I had a 3 el 40 full size on one of mine

I have mounted several towers in this fashion. I used some 40" face tower (two 20' sections mounted in cement) with about 35' sticking up, then fabricated a base to match the Delhi/Rohn HBX series an

My first choice for a home brew yagi would be one of the OWA designs by Jim WA3FET. http://nw3z.contesting.com/ or just do a google search. I use the OWA style of designs on 10 thru 80m. Two major ad

If there is a continuous path from one anchor to another, thru the guy wires (i.e. no insulators) you have a battery and current will flow - how much depends on the soil, wetness, ph etc. A rule of t

I have installed several of my towers this way, but no Rohn 55 or 65 experience. Weight is not usually an issue, but kinking the tower in the first moments of the lift is. Once more vertical the stre

I enjoyed meeting many of you and talking about rotators last year at Dayton and looking forward to more of the same this year. Due to fire regulations, they tell us we got moved a bit and we'll be a

I do not have first hand experience on this tower so can't answer completely. It will fit in Rohn 25 which looks like about the same face size as your top section on the TX-472. Our rotor doesn't hav

Well, that was quite a pileup! Thanks for all your questions and interest in the product. I have to QRT to start the journey to Dayton, so I won't be able to answer any emails until I get back. There

This is 10" Beatty (also named Wind Turbine at at one time, I believe) and now owned by LeBlanc and Royal. There is a heavy gauge and a much thinner one - you have the heavy version. It is long out o

Enjoyed the pictures and story on your web site. I wouldn't be at all concerned that you compromised anything - in fact, I've done the same on several of my towers. It's easier to shim to try and pul

With SAFETY in mind, do not always assume that a worm drive can never be driven by the load. Not all worm drives are created equally. A low ratio (15:1 possibly) worm can be driven by the load. I hav

I would suggest using the encapsulated sealed relays such as the Potter and Brumfield RKS-5DW-12 (about 8$ in Canada) or the lighter rated - and cheaper ($C2.50) Aromat JS1E-12v. Both have given exce

Barry and I have exchanged a few emails regarding specific features of the AlfaSpid rotator but I thought I'd mention a few things for the rest of the reflector. My first A/S unit has been up over 1
