[NLRS] towers

[Dave Aho]

This is mainly for Brent Casavant, as he asked, but anyone else can look too ya know...*L*
 
    The question was, what I used for towers....
 
the "easy tower" to put up and down is two sections of Rohn 20/25 with an NTE rotor attached to the top.  The base is on loan from W0AIH....it is a square metal frame about 2 feet on a side, made out of 2" angle iron....it has three points on it (two ar the pivot points and one is the locking point...each leg gets a steel bar bolted inside of it for this purpose.....I will try and get a picture of it sometime and post it on my website.
 
As for the Porta-tower, it is a Utility trailer with a wooden scaffolding set up to pivot two sections of Rohn 20/25 and masting pipe up.  The Yaesu rotor is mounted on an aluminum plate at the bottom of the bottom section...masting pipe runs through both sections of tower and a wooden thrust bearing at the top....I can put the 5 VHF/UHF/SHF antennas on the masting sticking out the top and it still raises easy.
