Hi Rich, For the last 40 years I have been using a 6 foot string at arm's lenth weighted by a crescent wrench to determine if my towers are vertical or not. I learned this trick from some power compa
My Silent Key friend, W7MB, had a wooden pole about 70 feet high in his back yard. He had a couple of cables running from the ground to the top of his pole that acted as guides for an antenna mount t
There's lots of things to consider here. Corrosion: I know that zinc (galvanized steel) and aluminum are pretty close together on the table of galvanic action so they tend not to corrode in the weath

Hi Dana, The answer to the question about whether you need to multifly your Force 12 numbers by 1.5 or not is contained in th following information: First, you must remember that both antenna makers
Hi Roger, I can tell you from personal experience that you can get Big Grips from PLP for 3/16" and 1/4" EHS. Maybe they are not available in Brazil and it sounds like you PLP rep does not have all t
Hello Roger, The cable you are describing does not sound like any EHS cable I have seen. The EHS cable I have seen, both 1/4" and 3/16", has 7 solid strands. I am not sure either Big Grips OR Utility
I think Rohn has done a LOT of things that don't make sense . . . so, yes, it is quite possible they did it again . . . Stan w7ni@easystreet.com that Yes, I think you are naive . . . if you put that
Hi Cam, This is very interesting information. Even though I was a Rohn Dealer for years, I never saw any plans for a 25G rotator self that would fit in 25G where there were diagonals installed. I als
The 25AG3 is my preferred pointy top that allows you to use a 2" OD mast. It looks stronger to me than the 25AG2 which is the other Rohn pointy top that allows a 2" OD mast. Stan w7ni@easystreet.com
I like it the way it is. I have been on another list that was the way you are suggesting and the result was tons of "junk" responses to the entire list that should only have gone to the sender. I don
I suppose you could take them to court over the fact that it does not meet the advertised "delay specifications" of 1/12000 of a second . . . You were counting on that match delay time for your ampli
If you guyed a 70 foot 45G at 4 levels and put the top set at the top, it would hold a HUGE load. I can't calculate how much since I am not an engineer, but you should find one and suggest this confi
As I understand it, each crimp on a Nicropress sleeve has the holding power of one cable clip. Each Nicopress sleeve has FOUR crimps. I think two are redundant. Take a look at a large commercial cran
Well . . . IF you do what the manufacturer says, you never use Nicopress fittings on EHS . . . only on 7X19 stranded cable. That is why you need three instead of just one . . . Stan w7ni@easystreet.c
I just happen to have one of the expensive crimpers that looks like a bolt cutter. Yep, it was about $150 and was 25 years ago. One of the things that the seller of the fittings showed me was a cut-i
I like Tom's suggestions for THOSE towers. The base problems with those towers was either rust or shearing. The tower in question had standing water in the leg and it froze, splitting the leg. The on
I did a pretty good search for the specs Rohn might give on the angle between adjacent guys and could not find anything specific. I did find the angle expressed as the following, however: "120 degree
It seems obvious to me that giving a "Anchor Alignment Spec" of 0.1 degrees makes it close to impossible to comply with Rohn's recommendations. Is this Rohn's "escape clause" where they escape all re
