For over a year now I have been using a SOTApole and 144MHz 5 element SOTAbeam. As the beam uses a plumbing U clamp rivetted to the boom, it always mounts on the pole at the same height. Recently I have noticed the pole is beginning to crack at that position. So does anyone know how I can reinforce / strengthen the glass fibre without affecting it dimensionally, i.e. without thickening the tube?
