Looking for a 140' Rohn 25G (Base insulated prefered) Also, a 100' Rohn 45/55, or equivalent self supporter. A retired windmill tower would do fie (if it is around 100' +/-) Thanx! Brian KE6IYC _____
I am morphing this 160 antenna project on an hourly basis..... Are there any AM broadcast engineers on the list? I need a rough layout of an ATU from a broadcast AM system. TNX! Brian KE6IYC ________
I can speak first hand to this issue, as being an off-grid home, my trace/xantrex inverter is a reliable and constant noise source from 1.7-2.5 MHz. Still working on a solution.... Brian KE6IYC _____
Before my inbox is flooded with basic information (which is appreciated!), let me give everyone some background... I am a television broadcast engineer, and have been working with all things RF for o
So you run illegal power? My understanding of the rules, is that you are allowed 1500 watts, PEP MAXIMUM. And just because folks do not have an interest in HF or contesting, does not make them any le
Mention was made of simulating with NEC to see what one would get from a particular stack. Assuming the results are not what one wants right out of the gate, how can one optimize the antennas to get
I am putting up 80 ft of Rohn 25. I am using the steel guys that are part of the extension to the AB577 system. The benefit is they are one-piece, adjustable in length and available to me since I'm t
I am having a little interaction between my TH-11 and my guy wires, so I am thinking of replacing a portion of the 1/4 EHS guy wire with some Phillystran. I cannot seem to find information on how t
That's WHOA, fellas, I'm only talking about using the '577 guys as temporary guys - one should NEVER think of using anything substandard for a permanent installation. That would, indeed, be asking f
I purchased eight sections of used Rohn 25G last summer and it's finally going up. While test fitting the sections, I find that I have one "stubborn" section - it will not go onto nor will it accept
AA battery x 2 = 3.0 VDC, seems like a small solar panel could be in order.... Sure would beat climbing the tower once a month to change batteries... Brian KE6IYC ____________________________________

I want to thank everyone for all the helpful and practical suggestions. I will first determine if the leg diameters are the same, then check alignments and do what I can with "gentle persuasion" to m
FYI: the jack in my 2004 VW Golf is perfect for separating Rohn 25 sections. The "tongue" has a piece of channel that engages the Z bar securely. I place a plank across the "opposing" Z bar to ensure
I was surprised to get a competent-sounding person on the phone when I called BoltDepot.com to find out what grade of steel is used for their hot-dip galvanized bolts. Having vastly exceeded my expec
No sooner did I decide to use grade 5 / zinc plated bolts, than I found a company called GME Supply with a limited range of 3/8" galvanized grade 5 steel bolts and overtapped nuts in exactly the leng

Perhaps a typo on their site, or an oversight, but how cane one have a turning radius (20 ft, 1 in.) LESS than the boom length (20 ft, 6 in.)? Brian KE6IYC ___________________________________________
I have obtained several aged yagis that I intend to rebuild. The elements and booms have various amounts of "gunk" on them - ranging from atmospheric crud to left over tape adhesive to oxidation wher
