Hi Shawn... I had screw anchors which I think I purchased from Texas Tower. They were probably manufactured by Rohn or some other well-known tower mfgr. IRC they were 4 augers on 4 3/4 (or 1?) rod, a
Shawn, You say the tower is an EZWAY. Do you mean the two or three section crankup tower with the wonder ground post? I had three of them over a 10 year period in the 60's. If you do: 1) The tower is
Any anchor that's exposed to soil is at risk of corrosion. Anchors sunk in concrete are just as vulnerable because typically a good portion of the anchor rod is not in the concrete -- it's in contrac
The alternative is to take a page from the bigger broadcast tower installations and encase the guy rods in concrete. 73, ... Joe, W4TV On 6/18/2013 9:13 PM, Dick Green WC1M wrote: Any anchor that's

So the answer, it would seem, is to have any guy anchor (galvanized or not) to not only be embedded in concrete, but in an elevated pier so that the entire guy anchor is 100% above ground soil. If I
SEE CAPS BELOW Wow. I wonder what the source of the corrosion/electrolysis actually was? DISSIMILAR METALS IS THE BASIC ANSWER; THE CHEMISTRY IS MORE COMPLEX, BUT THE FURTHER APART MATERIALS ARE ON T

That is good. How long are sacrificial anodes good for before you have to inspect, maintain, or replace? Costs? Labor? Do they have other unintended consequences? 73 de k0dan --Original Message-- Fro

Were your guy anchors grounded with a copper ground rod? Hans... In my experience this is not true. I have some photos of my failed galvanized screw anchor which I can send you. The failure was a goo

The power company uses screw anchors, but I think they are between 6 and 10 inches across with a 1 or 1.25" shaft. 73 Roger (K8RI) They also place an insulator in the guy cable to stop galvanic corro
