The Towers Tower #1
116 feet of Rohn 55G. Guyed for 90 MPH winds at 115, 77, and 38 feet to guy posts set 96 feet from the base of the tower. Guy wires are Phillystan, with 20 feet of EHS to attach to the guy posts. All guy wires are attached to the tower using Rohn GA55D guy brackets. The mast is 23.5 feet of 2" o.d. x .25" wall 1026DOM tubing. Antenna on Tower #1 120 feet of Rohn 55G M2 Orion 2800 rotator (2) Force 12 C51XR @ 118' rotating and 52' fixed to Europe (1) Force 12 C31XR @ 85' rotating on TIC Ring 1022E 80 meter wire dipole at 75 feet as inverted vee 160 meter wire dipole at 105 feet as inverted vee (3) Stack Match by Array Solutions for 3-antenna stacks on 10, 15, & 20 (1) Stack Match by Array Solutions for 2-antenna stacks on 40 Fed via 6 runs of 1/2" hardline to tower base, then JefaTech LMR400 equivalent up the tower. Radial field of 40 radials, 125 ft long, in preparation to shunt feed the tower on 80m and 160m. Tower # 2 (planned, not yet built) 70 feet of Rohn 55G. My plans for this one are not complete as yet. I am considering using what I have on hand now: - KLM KT-36XA at 72 feet, rotating - Covers 10, 15, & 20 meters
- M2 KT-34XA at 38 feet, fixed toward Carribean - Covers 10, 15, & 20 meters
Tower # 3 45 foot home-brew foldover pole 
Antenna on Tower #3 Lightning Bolt 2-element 5-band cubical quad, rotating on Alliance HD-73 - Covers 10, 12, 15, 17 & 20 meters 80-meter 4-square suspended from Tower 1I'm considering an 80-meter 4-square to be suspended by ropes from Tower 1. However, the geometry of the antennas may prevent it or severely distort the pattern. Here is a PDF of the proposed installation, drawn to 1/8"=1 foot scale. The base of the verticals will be 48 feet from the base of the tower. Link to the PDF file What are your thoughts? |
