Criteria for antenna site
(a) Using a pole up to 9 cm in diameter and resistant to hull vibration
If the antenna is to be mounted using a pole such as a handrail, reinforce the pole by providing
stays so that the antenna can maintain its initial anti-vibration characteristics.
(b) There should be no obstructions within a radius of 1 meter of the installation location. The
presence of any obstructions may bring the whip antenna into contact with them if it is swung
significantly by the wind.
(c) The installation location should enable the antenna to be completely waterproofed.
(d) The installation location should be sufficiently distanced from the antenna of the transmitter.
