[TowerTalk] Tower Junction Box

[Les Kalmus]

  I am adding additional hard line to the runs I already have and I need 
to get a larger junction box for the cable termination at the base of 
the tower.

Anyone have an idea where I can find a junction box or NEMA box that is 
larger than the usual 12"x12" pvc and won't break the piggy bank?

All the NEMA boxes I can find on the web seem to be very expensive.
