Excellent stuff for aluminum. I had it sprayed on the innards of my airplane annually for years - no corrosion. It will wash off - it has the consistency of light oil. At the aviation shows, they use
Magnetic declination is different for different places on the earth, and it is changing at an increasing rate. Some geophysicists believe that we are approaching a "pole swap" event, like the earth's
If it is good shape, meets your load requirements and you don't need an engineering effort to get permission to put it up, go for it! The top section is the weakest like - don't overload it with ante

I have seen several Force12 antennas that have failed in my part of the world in a tropical salt water environment due to corrosion and mechanical wear from wind. If I were assembling one, I'd be tem
1. Aluminum and stainless steel are dissimilar metals and will corrode when in contact with one another. 2. The physical construction of a screw is that it has fairly sharp ridges for threads. When i
K9MBQ offered great advice: "IVO the current mkt, don't be shy!!" HOAs are interested in the long term financial health of the properties. Getting an explicit statement from the HOA about an "amateur
I am finding it interesting to engineer a way way to attach things to a crank up tower. It looks like the cable standoffs are done with small U bolts. I'm considering having a light plate made to bol
I'm DEFINITELY going with a set of KF7P's curved standoffs. I think that's my best protection against feed line entanglement, given the characteristics of winds here. There are lots of great ideas he
I've done business with MGS many times over the years and find them to be honest, inexpensive and generally a great place to get stuff. If I were going to buy a 43 foot pole, I'd buy two or three MGS
I've owned both... but not both at the same time, nor the same site, so take this for what it is worth. I owned a TA-33 in the late 1970's and an EXP-14 from 1985 until 1991. The CL33 is simple to co

I'm looking for a source for a dozen or so liquid tight cord grips for LMR-400 size cables... I'm building boxes for outdoor switches and SPG for my ever-so-slow tower project. I thought $7 for the H

A wiring diagram is easy - Leeson has them on their web site. I used the Leeson washdown duty motor - it will last longer outdoors. Reliably switching the motor requires a hefty switch. I deployed a
Hi, Dave, The power of the sun over time is incredibly more powerful than a bullet. UV degradation occurs to Lexan, degrading optical properties over time, however I know of no studies concerning str
Mine leaks. I top it off every few months and clean up the drips with an oil absorbent pad. It leaks about 2ml/month it appears, so I'm not overly concerned. There IS a stain on the tower base, thoug
Motors are a bit funny. When they start, they present a very low resistance, allowing the current to rush in and create the field that starts the motor - when the field is created, the field provides
Hi, Doug, IMHO, the DPDT switch originally fitted to my tower was insufficient, given that it lives outside (in my case) in a tropical marine environment. Current can kill one of those dpdt toggles v
