Below is an example of a tubular mast with a directional antenna and a rotator on top. In general, I recommend guying masts in two or more levels. Of course, it depends on the specific mast, but I roughly recommend one level for every about 5 m (15 ft.) of height. In this example, the mast is 12 m (36 ft.) high and made of steel tubes 50 mm ( 2") in diameter.
What will you need?
- Rope. Based on calculations Forces in guy ropes and other considerations, it came out as a good solution the rope Mastrant Mastrant-M 3/16" (5 mm). It is strong enough with a huge reserve.
- Mast clamp. I recommend ACM1310, 2 pcs = 2 levels. I suppose you will guy the mast in 3 directions - you need to keep the angle of 120 degrees between guys relatively accurately, no more than 5 degrees deviation.
- Connecting element for the guy and the mast clamp. I recommend a Chain link coupler, size 6 mm. You need 6 pcs.
- Thimble and clip for the upper termination. For 5 mm rope, you need ATH05 and ADC05. You need 6 + 6 pcs.
- Connecting element for the bottom. I don't know what kind of anchoring into the ground you plan, so it depends on your particular solution. I can recommend these anchoring solutions or similar. For attaching the rope, I recommend again chain link, but a bigger size, 8 mm – ACC08. You can also use the shackle for bigger anchors. Again, 6 pcs.
- Tensioner. I recommend a popular cleat tensioner - for your rope CL223. You will need 6 pcs.
- Clamp for securing after the final tensioning of the guy ropes - the same as for the upper termination - ADC05. Again 6 pcs (so toal 12 pcs).
