Guy wire installation9/2/2023 ![]() ![]() ![]() ![]() Here are some real world installations and our pole strength test results. The first point to make in this article is are you sure you really need guy wires ? Two inch diameter poles, particularly the thicker 14 gauge/2.0mm type, really are quite strong and scaffold poles are even stronger. It should be borne in mind that this actually puts more strain on the wires and anchors due to the leverage effect of the unsupported length of pole above, but despite that (and the not recommended use of screw eyes as anchors ! ) it’s still there having been put up in 2001, having survived some vicious winds…. We reckoned (correctly as it turned out) that supporting it half way up the pole would be sufficient. We couldn’t be arsed to take the whole install down to get the hook collar at the top ! Note : standing on the chimney is not advisable…. Also, our install is actually “semi stayed”, this is because it was done in a bit of a rush (the wind was whipping the pole around like nobody’s business) which resulted in, to be frank, a bit of a bodge. Most cable stayed transmitters are not firmly fixed at the bottom, they’re mounted on a ball (tubular masts like Winter Hill for instance, are not). Actually, in one very important respect, they’re rather different. Guy / stay wire supported masts, your aerial pole or a TV transmitter, exactly the same principle ! See ATV's aerial array and Ridge Hill transmitter (in the picture below). ![]()
