This Antenna is a four element, 6 meter Beam optimum spaced for maximum forward gain. The beta match system allows the best possible match to coaxial cable with the broadest possible pass band.
This antenna includes stainless steel hardware for all electrical and most mechanical connections, and a boom-to-mast bracket that will fit masts up to 2-1/16 inches in diameter.
