NOW IN STOCK
This is the younger brother of the SG-230 with three major differences. The first is that it operates from
 1.6 to 60MHz, the second being it is about a quarter of the size of the SG-230 and the third
is the maximum allowable RF power is 100W PEP. Once again the tuner is fully waterproof
to a depth of 500mm
 
This is an ideal mobile tuner to use with commonly available radios such as the Icom 706/7000
 and the Yaesu 857. It can also be used with several models of the Codan and Barrett
commercial HF mobiles.
For use with any of the following antenna -
  •  
    • Whip
    • Backstay (marine, sail)
    • Dipole, centre fed
    • Dipole with feedline
    • Loop (small) 2 x 2ft multi-turn
    • Loop (large) 10ft and up single turn
    • Longwire
