Building a new atenna at N6QW ~ Part VIII

Approach Resolved ~ A Good News Story!

I am happy to report that I have a new path for installing my new Tri-Band Beam antenna. Here is the plan.
  1. The new antenna will use the Spider beam 10M Heavy Duty mast as the support structure.
  2. The mast will be bottom rotated using a Yaesu G450 rotator.
  3. The rotor base section will employ a US Tower RP-3 base plate section that is normally installed in the top section of the tower but instead will be installed on a concrete base. My approach involves elevating the RP-3 base plate assembly approximately 3 inches above the concrete base to enable access to the rotor wiring. The elevating mechanism will be 3 inch steel angle stock which will be anchored to the 1 foot cube reinforced concrete base using 8 X 1/2 inch anchor bolts.
  4. Spider Beam was able to set me straight on how to route the coax so it does not get entangled in the guy rings.
  5. This has added immeasurably to the cost but will provide a solid installation. I only regret that I did not think of all of problems before purchasing some of the hardware that was initially bought. Someone will get a good deal on a Rohn H950 Mast and other associated hardware.
  6. I will post progress photos during the construction.
