[TowerTalk] Vertical on 80

[Chris BONDE]

I have looked at them.  Here they only come in 10ft sections.  Longer may 
be available but at a price.  The ones that I have looked at seem to have a 
thin wall, not very strong.  I donot know what alloy Al.

I have been told that the best is the long lengths of exhaust pipe, galvo 
inside and outside and strong.  Different sizes swedged could make a good 
vertical but how I?

Another that I was looking at was electrical piping, the stuff that is used 
for the stack on the roof.  It is also available in differenct sizes but is 
expensive.  For my re-service the pipe was CA$60 for 10ft. plus taxes.
