No. 8

This Bell Helicopter 214ST, operated by Okanagan Helicopters Ltd. of British Columbia, Canada, carries a Collins PAC-200 automatic probe antenna/coupler. Connected to an HF transceiver it has been used continuously since late 1982 on flights out of Halifax, Nova Scotia, to off-shore oil exploration platforms as far out as 350 kilometres in the Atlantic Ocean. The self-contained unit avoids problems associated with the long- wire antenna installations previously used.
