Yes, you're wrong. Aluminum antennas at some of these hostile environment QTH's only last a year or two - the towers maybe 5 to 10. I'm sure there are more horror stories. Cheers, Steve K7LXC TOWER T
I'm sorry you were mislead. I have found that few dealers actually know much about their tower products, let alone actually install one. While "flimsy" isn't an engineering term, the towers are compl

It's a 19-year old CD45 - one of their 'brakeless wonders'. In excellent, refurbed shape it's worth about a hundred bucks or so. Cheers, Steve K7LXC TOWER TECH
They also had articles on masts made from irrigation pipe - doesn't mean either design is worth doing. A bunch of farting around with materials designed for something else with questionable erection

Calculate? How would you come up with a formula for the tree capacity? I've installed 14-15 antennas in trees including HF yagis and 2L 40M beams so I have a professional perspective but don't have a
Well, I only have experience with the fir trees here in the Pacific NW. I've never seen a tree die because of being topped but I'm not an arborist. Maybe 12 inches. It just provides some resistance t
DO NOT strip the limbs - big mistake. The tree still has to have growth at the top in order to bring up sap; no limbs, no growth, no sap - wood rots and antenna falls down. Yes - or what. I usually h
For fir trees here in the Pac NW with some minimal growth left, they'll last indefinitely. Tree tar doesn't seem to make any difference here but YMMV. Not in my experience. Everything below the anten
LM470D Since they were both designed by Louie Tristao, KG6VY, SK, it would make sense that they would be somewhat similar. He also designed the Wilson crank-ups. Cheers, Steve K7LXC TOWER TECH
