    Question about anchor placement. I'm putting up a 60' Rohn 25g tower and I have room for 2 anchors at 50' from base and the other 1 20'. screw in type anchors, will this work?

    No IMO!!! You want to have at least 2-3 sets of guyed wires in groups of 3 or more, coming down a tower that size and also all other proper or needed things for installing a tower that tall. I could be wrong, but I doubt it ok this one. I wouldn't trust 2 long and one shorter guyed wire for sure!!! Don't skimp out when placing a tower this high up as you have to now realize that you have at least 80-100ft of total tower, mast pipe, and antennas. If it falls, will it take out your house, cars, and so on.
    You want to build yourself some concrete pillars, or pour concrete for the guyed wires, and also make sure the guyed wire you use is rated for the tower height abs weight. You can most likely find a lot of info on Rohn's web site as to how properly guyed a tower of your size. If not them, look up how commercial guyed towers are done. JMHO's.
    Like I said, I wouldn't be so crucial of this, but you don't want to have a tower in your house or on your vehicle and so on. That is if it's that close to the area. These are JMO's, but I am pretty sure about what I am saying.
    Be safe, and have a good day.

    According to the Rohn specs for guying 60' of Rohn 25 you need to guy it at the 28 and 55 foot levels and the guys should be evenly spaced 48' from the base.

    Thanks for the info I was going to use 2 sets of 3 wires but what can I do about the short wire because I have no more room on that side. By the way I'm using a hazer on this tower.

    Move the tower. That's about all you can do. Can you show us a drawing of your layout showing the ptoposed tower location and the proposed anchor points as well as anything in the way preventing you from putting the anchors where they should be. This is another reason why I personally despise guyed towers. Freestanding towers are more expensive but so much easier to install and more esthetically pleasing.

    Thanks guys for all the good information but I've solved my anchor problem with help of neighbor. My next question is about 3/16 steel coated cable. I already have every thing I need to use this stuff but do I need to strip the coating where the big grip dead ends will be attached?

    I would say yes, to avoid any slipping or hidden rust issues that might arise, But I could be wrong. Also add something for rust as well. NO-OX, or something similar. You want to make sure that you don't have a fault at that point for sure!!! Be safe and take your time. Have a good one.

    I'm not sure about coated guy cable. When water finally gets under that coating I think the cable will rust and fail sooner.

    Are you talking about these type of dead ends?

    [​IMG]

    If so then YES YOU MUST STRIP ALL COVERINGS!! These dead ends intertwine with the lay of the cable to provide grip and you MUST wind them the right way so they lay in the grooves and not across them. Also MAKE SURE THE DEAD ENDS ARE SUITED FOR THE TYPE AND SIZE OF GUY CABLE. These are meant for use with galvanized EHS type steel guy wire and using them on anything but the proper cable WILL result in them pulling out and causing the tower to fall. If your cable has a coating I cannot imagine that it is of the right type. FWIW I spent 22 years in commercial broadcasting and have used these many times on all our towers, eight AM towers and two FM towers as well as several VHF/UHF towers. Make sure you have the proper stuff and know how to install it. Sorry for the caps but this is a MAJOR safety issue here.
