[LW] [LW11] AIS700 - range

[Louise - Raymarine - Moderator]

Dear Kr7,

Thank you for your post.

The AIS700 is a Class B 5W transmitter, which will “Transmit” your position to about 8Nm depending on your VHF antenna (note, fibreglass are less efficient than whips).

In regards to Rx targets, this will very much depend on what AIS they are using – older Class B AIS units were only 1W and therefore do not have the same “transmission” range as the AIS700. Therefore the range that you are viewing is entirely dependent on the AIS being used by the targets you are viewing.

Many Thanks
Louise
