Antenna Mast Manufacturers recommend guying masts of ten feet and above in height. When Selecting Guy Wire for use in Guying Antenna Masts, Consider the Height, Antenna Size and Wind Loading being presented. This Stranded (6 Strands of 20 Gauge wire) Guy Wire is Just fine for Most all Antenna Mast Guying Scenarios, However, We recommend that You consider using this wire for Shorter, Lighter Load Applications.
