150ft tower usually requires more that two sets of guys but we want to used large stacked array and therefore this tower uses only two sets of guy wires.

The guys are 120 degrees spaced with at 50% of the mast height for the upper set.

I think that when using AB105 sections this will be strong enough to eliminate possible mechanical resonance in the mast and two wires will be sufficient to case the tower to vibrate.

The last 6ft of the 55ft guy wires are fastened with 10mm (0,39") stainless steel wires. The turnbuckles are half tensioned.

The last 6ft of both guy wires are fastened with 0,39" stainless steel wires. Both guy wires are 11023lbs and 0,67" in diameter.

On the right you can see the 30o and 60o wires attached to the concrete. Everything is waterproofed by the special Shell lubricate.

TENSIONERS: The turnbuckles will be attached with tensioners. These plates are 500mm long, 50mm wide and 5mm thick. All holes are 18mm

A closer look at the method I use to fasten the turnbuckles to the tension plate. Double nuts to secure the bolts. 

Just visible is the extra eyebolt which we used for temporary tensioning. On the below picture both terminals are 10ft from ground level for safety reasons.

The stainless steel ropes will be used between the guy-tensioners and the 16mm Parafil guy wires.
