radar equipment was put on the world's markets in September by Kelvin Hughes (Marine), Lid. Known as the Type 14, the new radar has several features. For instance, the scanner unit incorporates a slotted waveguide radiator which eliminates the necessity for the conventional reflector. The use of this system is claimed to reduce wind resistance and weight considerably, whilst at the same time the electrical characteristics are greatly improved, and sidelobe echoes are eliminated. The transmitter unit, which measures 16 X 15 x 9 in (406 x 381 x 229 mm), is designed for bulkhead or deckhead mounting. The display unit is compact, incorporating a 9-in (229-mm) C.R.T., and is suitable for deckhead, bulkhead or deck pedestal (229-mm) C.R.T. used provides an exceptionally information in turn la recorded If not prepaid a booking fee mounting.
