Personally I like insulated, stranded 18 gauge wire. I've found 5000 ft spools on eBay for real cheap. I like this better than 14 or even 12 gauge since it's light enough to not retain much memory bu
Lightning isn't gonna care about that insulation; it'll blast right through it. Phil KB9CRY And, you'll have a separate, extensive lightning grounding system in place anyway, right?!! -- Original mes
And, I wonder if one were to file a claim and the insurance company asked to see a copy of the building permit......what would happen if one couldn't be produced? Phil _______________________________
I agree, ask your agent. My personal contention is that if you're pouring structural concrete, as in the tower base, you should be able to pull a permit for that. Does your township require a permit
And, if I may make my regularly scheduled transmission of safety information concerning fall protection. One poster mentioned that he only used a rope lanyard rather than a shock absorbing lanyard, w
Sure enough, when mounted at the weight balance point, there is more boom on the front end than on the rear end. What works for me is to keep the antenna with it's rear pointed into the wind; the lon
Thicker steel usually means stronger so therefore the difference in specs. If you want to see if 45 will do a better job if guyed heavier then you need to get a structural engineer involved. Always f
I personally second Gene's opinions on Trylon. I love mine also and it loads up on 160 great for me too. Go with AN if you need the extra specs for you application but if the Trylon will do the job;
I'll take a stab at these questions, based on my learnings. Personally I use ICE devices in my installation and have thoroughly read through all the related Polyphaser and ICE articles, plus others.
Doing a Google search for Rohn yields the Rohn website at rohnnet.com. From there one can access the online catalog which has all the Rohn drawings, diagrams, etc. The info in question can be found o

A trick I've seen lots of folks use is to attach one half of an automotive CV joint cover. It's rubber with a bolted connection down one side so it can be opened up and wrapped around the mast just a
You guys know my vote = AlfaSpid. For the same price, worm gear drive, no brakes to break, no mechanical stops to get jammed up against, no plastic gears to break, no pots to get dirty. Mine's been t
Another consideration to give is how often do you mind going up the tower and possibly servicing the rotator (proper spelling, rotors turn points and rub up against brake pads) and possibly swapping
There is only model of AlfaSpid. The different specs are there and depend on what voltage you feed to it. It'll take anywhere from 12 to 24 volts. The more voltage, the faster it turns and the more t

No, you supply the power supply. Personally I have mine hooked up to a Pyramid 5 amp 0-30 volt power supply feeding my Spid over 500 ft away via #10 Romex wire (UF outdoor rated, you only need four w

The EWE is ground dependent; if you have good conductive ground, it'll work well. The K9AY loop as well as a pennant/flag/delta loop is not ground dependent. My EWE's worked well but too close to the
I strongly support doing the M2 upgrade. It replaces those plastic linear supports with bullet proof aluminum blocks. Makes the antenna very rugged and should last a long time. Phil KB9CRY -- Origina
