Subject: [TowerTalk] Rohn 45G Guy Lug Sections

Passing on to reflector for informational purposes:  I received responses from Rohn to my questions regarding the 45G "Guy Lug" sections, the 45GL-2 and 45GL-5 they are termed. It appears some Rohn dealers are mistakenly calling these "ground lug" sections. When the larger 5/16" guy cable is called for on the 110 and 130 MPH 45G designs the 45GL-2 (lugs 2' up from bottom) or 45GL-5 (lugs 5' up from bottom) lug section is required in order for the guy bracket to rest on the lugs in addition to resting on the horizontal brace. Otherwise this guy lug section is identical to a standard 45G straight section.  I admit my lack of knowledge in this as I have never heard of or seen a 45G guy lug section. A pair of lugs are welded to each leg in appropriate locations for the guy bracket members to rest on. What is concerning to me is that if you want to use a different top section (other than the 45GL-2 or 45GL-5) you are out of compliance with the use of the guy bracket and 5/16" guy cable. In my particular case I like the heavy wall 2" ID "neck" type 45G top section of which is not available with the guy lugs welded to the legs. I asked Rohn for advise regarding this and the answer I received was that if I wished to use a different top section than the 45GL-2 or 45GL-5, in a 110 or 130 MPH rated 45G installation, then I would have to use the services of an engineer to design the tower guying system to utilize smaller guy cable (to avoid 5/16" top guy). I am curious if any other 45G users have dealt with this before? Things sure have changed over the last several decades in regards to these tower designs; I was looking through a mid-1980's Rohn tower manual (the large two-part amateur/commercial one) at 45G designs and it is sure interesting to note the difference in materials used in older designs (newer deigns = heavier/stronger materials).Byron W5FH
