In 2005, NAV CANADA’s radar coverage of Hudson Bay was limited to line-of-sight (LOS) and did not cover the entire Hudson Bay area. The Company used VHF communication sites around Hudson Bay and HF communications for areas that were not covered by VHF. During a testing phase, the system produced a result that was less than expected as the coverage was effected by ice buildup on the antenna. Sinclair Technologies was approached to provide a high gain antenna that would be able to withstand ice buildup and to provide the expected coverage.
