MA 2-1 SC-SHT
Marine VHF Antenna with reduced height
Description
- 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, such as windex, supporting wires etc. Free mounting and as high as possible is preferable, otherwise the VSWR and the radiation diagram will be influenced.
