[TowerTalk] TH-7 10M Dire

[TexasRF at aol.com]

The decimal value for any fraction is the top number divided by the bottom  
number. 7 divided by 16 is .4375. neither 3/8" or 1/2" tubing will work for 
 that.
 
In over 15 years of selling aluminum tubing, the only user of 7/16" tubing  
I have seen is Hygain, for their element tips. So, you might give them a 
call  and get pricing on their 7/16 inch material.
 
7/8" tubing is .875 decimal; plenty of that available. The usual wall  
thickness is .058 inches to allow telescoping of adjacent sizes.

Hi  Everyone, 
I am missing one part of my TH-7 10M Director...I see that  
DX-engineering/Texas Towers has the tubing parts, but the size is what I am  not sure of. 
The TH-7 manual says it's 53" of 7/8" tubing for D1 and 43.5" of  7/16" for 
D2, but dx-engineering/TX-twrs uses decimal points not  fractions...so, 
anyone know which one would be equivilent and is the manual  talking about O.D, 
or Wall or what? Probably O.D. 

Thanks,
Daniel  N9WX
