Tessco makes a nice one that has a collar that goes around the vent hatch on
top and no welding ,very secure.we bought one approx $2,500 and had a local
machine shop build us two more at $500 each.They work real w

I remember a while back somebody showed a very nice design of a collar
that went around the hatch neck.

Magnets don't lose their magnetism unless heated to very high
temperatures. In warm temperatures (achievable at the top of a water
tower) it may lose a little bit, but it returns to normal once it is
cooled.

Are the magnets the best (most cost effective) way of completing this type
of install? Or is capacitive discharge stud welding going to be the better
route?

Do a little reading on rare earth magnets (the strongest magnet there
is). You might be able to do some calculations and figure out what you
would to build your own.
Here are a couple sites I just googled. I think all you need to do is
figure out how much pull force you need to offset the wind
I have two water towers that will need 4 to 5 antenna mounts. The water
towers are both the same. They are approximately 120' with a climbing tube
and a bulb at the top. There are no side rails. The hatch opens to the bulb.
How do you attach antennas??? Is welding standoffs the best practice? Any
