Telescopic fiberglass masts are a popular option for portable antenna supports. However, as 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 for a mast. This makes it very easy to compare different products.
