To tighten the guys, I use a preform about 6' up each guy wire and a come along attached to the preform (lever end of come-along). The cable end of the come-along hooks at a convenient place on the anchor or equalizer plate. Make sure the tower is vertical to the first set of guys via 4' level (what I use) or plumb bob (never tried this).

guy wire tension; There is a way to “calculate” the tension on a guy wire by shaking it and timing the pulse up the wire and back. It is based on the length, diameter and air temp. does anybody know the formula? Mike McCabe N9GXW [email protected]

Tensioning Guy Wires Created by Bill Fisher, W4AN (SK) and Mark Lowell, N1LO on 2007-10-04 "Editor's Note: Due to the popularity of some of eHam's older articles, many of which you may not have read, the eHam.net team has decided to rerun some of the best articles that we have received since eHam's inception.

1/4" EHS guy cable is rated at 6700#. 3/16 EHS is rated at 3990 pound strength. Phillystran is a non-conducting guy wire material made out of aramid fiber and is like Kevlar - strong and lightweight. It comes in different diameters and strengths. It appears Texas Towers may be the only Phillystran supplier in the ham market.

K9KJM Rating: 2007-06-04; Good Product Time Owned: more than 12 months. Phillystran is indeed a good product, And really not any more expensive than using egg insulators to break up guy wires into non resonant lengths.

When tilted over, the yagi hung over the gable end of the garage and was easily accessed in the driveway. I would easily manually tilt the mast up, grab the backstay guy wire, walk it out to the other end of the garage, and attach it. I used 1/16" diameter 19-strand stainless steel wire rope.

All the parts were there and fit correctly (with a little tweaking). The antenna is mounted on a 16ft 2" galvanized pipe attached to a the factory tilt base assembly. The tilt base is mounted to a 4ft section of galvanized pipe set in a 3.5 x 2ft concrete base. Because we have a strong sea breeze everyday I used the 3 point guy wire kit.

C. Site Location. These antennas need to be as far as possible from any surrounding metal objects. Our tests, and those of customers, show that any antenna wire should be at least 15-20 feet from gutters and metal house siding or fascia. Metal guy wires should be "broken-up" with insulators at non-resonant lengths.

(Depending on the band) I have worked it 80-10 in horribly poor conditions barefoot and over the last month, worked the world on FT8 with over 1K confirmed QSO's. Get one and pay attention to the instructions (or have a friend help) Also a good idea to …

Feb 12, 2025 · I hired Sullaway Systems for a complex antenna installation: two stacked c31XR JKs and one JK 404C on a single 90' Rohn 45 tower. After building the tower with a star guy bracket at 80', Marty and his helper Quincy set up a tram and got all 400 lbs of antenna in place without a hitch. Marty knows what he's doing, and his prices are very fair.
