Antenna
On sailing vessels the antenna can either be an insulated backstay or a whip
antenna mounted vertically, usually on the stern. Best performance will be
achieved by using an insulated backstay as the radiating length will be longer
than that available when using a whip.
NOTES:
•
The top insulator on the backstay should be approximately 300 mm from
the mast and the bottom insulator should be at eye level above the deck.
•
The distance between insulators should be greater than 10 metres and less
than 35 metres.
•
A whip antenna is generally used on small to medium sized power vessels.
There are different length whips to suit the vessel length.
