Procom 0.55m Marine VHF Antenna with reduced height The efficiency is very high despite the small dimensions and the antenna is fully capable of handling up to 50 W of output power. The tapered, reduced, incapsulated ½ λ copper wire radiator together with the chrome brass housing and stainless steel corner bracket constitute an antenna tough and ready to cope with the corrosive environment at the masthead or other places. The end-fed dipole principle makes the antenna independent of ground-plane, radials or other auxiliary arrangements. The antenna whip should not be mounted parallel or near to other metal parts, SPECIFICATIONS ELECTRICAL -MODEL MA 2-1 SC-SHT -ANTENNA TYPE Reduced ½ λ dipole, end-fed -FREQUENCY 156 – 162 MHz -IMPEDANCE Nom. 50 Ω -POLARIZATION Vertical -GAIN -1 dBi -3 dBd -BANDWIDTH 6 MHz ≤ SWR 2 -SWR <1.3 @ f.res -MAX.
