Description
The SM42 (Aluminium) is a 6dBd gain 2 stack folded dipole antenna array. Mounted on a 50mm Ø support pole with all antennas in the array at ¼ wave antenna to mast spacing producing a cardioid radiation pattern. All coaxial cabling, including phasing harness, running internally inside support pole thus reducing any damage resulting from otherwise exposed cabling.
The antenna array is DC grounded for lightning protection and is vertically polarised.
