Telescopic fiberglass masts are a popular option for portable antenna supports.
Telescopic fiberglass masts are a popular option for portable antenna supports. However, because they vary widely in strength and stiffness, it can be hard to compare them. SOTAbeams has developed a simple metric that allows an objective comparison to be made.
The SOTAbeams Mast Rating System (SBMRS) uses the length and the weight of the mast to calculate a strength figure. This makes it very easy to compare different products. Details at:
Campsites can give the perfect opportunity for some portable radio operating but using a mast within the constraints of a typical site pitch can be difficult. SOTAbeams has overcome this problem with the introduction of their suction clamp kit. The kit consists of two specially selected suction clamps, a plumb line, hook and loop tape and a 22mm adapter. The clamps can easily be attached to the sides of a caravan of motorhome and provide a firm support for a mast.
