  Very timely question.  See the latest issue of QST for information on how to 
protect your anchors.

  There is also a lot of information on the Internet on how to protect anchors.

  Here are some sites to look at:

  Interestingly enough, I will be adding cathodic protection to my 145 foot 
Rohn 45 tower this weekend even though after 9 years, there is no evidence of 
anchor corrosion (primarily because my guys are insulated and not grounded at 
the anchor points).

  I have installed the standard Rohn GAC303 guys anchors into buried concrete 
  per the Rohn drawings.

  I was talking to a tower installer who says that he has seen theses buried 
  guy anchors eaten away in only a few years.

  Thinking about this I imagine that if the ground was acidic it would eat the 
  galvanizing zinc of the steel rod very quikly and then the steel below would 
  not last very long. Would it be a good idea to protect against this by 
  applying lime at regualr intervals around the guy anchor to increase the 
  soil ph?

  I think that I am OK since I have pulled 8 foot copper ground rods that have 
  been in the ground here for several years and they came out shiny and
