This is, for the moment, a theoretical exercise.I am exploring the concept of reducing the potential points of failure and complexity. I do own a rotator. ;-) 10' is the separation number? So if I stagger the beams vertically, each with reflector close to the tower, 10 feet apart facing separate directions I should eliminate the interaction? This is more vertically efficient than 20 foot separation -- necessary when the beam centers are in-line. So, how does this arrangement look: Northeast on a mast at 65' Southeast off the side at 55' South off the side at 45' I believe I have the necessary hardware to support the side- mount beams should I elect to do this. The strength issue of Rohn 25, Rohn 45, or Rohn 25 reinforced with a second Rohn 25 is a separate consideration. I also have a couple of 50' Rohn push-up poles on which I could mount fixed beams ... but that adds coax routing complexity and the push-up poles are much weaker. -- Thanks! & 73, doc kd4e West Central Florida 100% Linux.
