[TowerTalk] Guy Wire Anchors

[Fredrick Matos]

Tnx Tim.

For background, I am PVRC, and I have had discussions with club members on my plans.
W3LPL has provided good advice. Also had helpful emails with Don Daso and Jon Zaimes.  

I had some interest in the American Earth anchors, but I posed my question more to begin a general discussion on anchors than  my application.   But if there was a very positive response on the American Earth anchors, I would consider using them, pricey as they are.

You make a good suggestion to connect with manufacturers and follow their plan, but it’s not doable in my case.   I am putting up an Army surplus AB-621 tower/mast. It came without guys, so I am planning the guys right now, and will buy Phillystran, Big Grips, etc. from DXE, around $500-600, maybe more. 

 The original 621s were  used for microwave dishes, like 4-ft diameter, but my plan is to use a SteppIR DB18.  The Army guys were 1/8-inch stainless, but I will upgrade and use Philly 4000 and 3/16-inch galvanized wire.  Other PVRCers use the 621s for SteppIRs, 40-meter beams, etc.  I even visited  a couple installations.  Thus there is considerable  knowledge based  on PVRCers experiences in using them.

Hey, I would appreciate the Dayton Hamvention discount on my buy.

73,

Fred W3ICM

The pullout  specs on the American model PE46-guy are very impressive when compared to the anchors with single discs.  I don’t know if Rohn provides pullout specs with their anchors, but they should.
