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
