<< The question is abt guy wire "What size to use"
 
 I see Rohn models Rohn 25 and 45 with 3/16" and 1/4" guy cable.
 
 My plans.....
 
 100' Rohn 45  with 4 element KLM 40   using 4 sets of guys
 100' Rohn 25  with 4 element 30 fullsize   using 4 sets of guys
 100' Rohn 25  with 2 element 10-20 quad   using 4 sets of guys
 
 Is 3/16" ok or should I use 1/4" ? >>

      The first thing you need to do is to determine what the windspeed rating
for your county is. Go to http://www.championradio.com and look it up. In your
case, Lewanee County, MI, is a 75 MPH windspeed zone.

       Next, get the Rohn catalog and look up the tower and the appropriate
height for the windspeed. (Hint: the Rohn catalog is available at the same web
site.)

       This will tell you what the proper guy wire size is. You can use
slightly bigger guy wire (1/4 instead of 3/16) but you'll never go wrong by
observing the LXC Prime Directive: "DO what the manufacturer says".

      Another hint: be sure to tension it correctly. 

      A WEALTH of information on this and other topics is in the TowerTalk
archives at www.contesting.com.

       Be sure you use EHS (extra high strength) cable (see LXC Prime
Directive above).
