This is the 2.5m UltraGlass antenna with glass filled nylon base. The extra height that this aerial provides can mean that the antenna gets a better all round clear view and therefore maximises its performance. The cable is hardwired to the Pro Series mount, so that the antenna can be easily removed from the base without pulling or cutting the cable. Can be folded down when not required, and installed on side or deck. SeaMaster Pro Series antennas are an excellent choice for new installations on small to medium sized boats. Robust, reliable and good looking, they will provide outstanding performance for years.
