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 SWR and the radiation diagram
will be influenced.
