AIS service restored

AIS service restored

WVHFG Categories

Today the Rangituhi - Colonial Knob AIS service was restored to service after a failure of the VHF receiver.  Coverage from the site has been gradually deteriorating over the last few months. 

Last weekend a working bee installed a new VHF marine band antenna at the site.  The new antenna is a PD220 Celwave Super Stationmaster with a gain of 5.25 dBd (7.4 dBi) arranged with a 6 degree electrical downtilt.
