Optional KA-07 GPS aerial with 10 metre cable



KA07 GPS antenna can be supplied as an upgrade option if an external antenna with a long length of cable (10 metres) is needed. Can be installed in place of the supplied 39A GPS antenna together with a BNC to SMA adaptor if GPS reception is not 100%  or just use an existing GPS antenna with the adaptor. Whilst the supplied GPS gives excellent results, any antenna is only as good as the signal it receives. Deep down in a boat, particularly one constructed in steel or alluminium, an external antenna may be required.

* free freight exclusions

We would like to offer completely free freight with every sale to anywhere but, sadly, this is simply not possible. Generally, if you live in mainland UK in a populated area freight fees are manageable, however, to Highlands and Islands, Isle of Wight and what freight companies call remote areas, the cost can be quite high. However, if you live in one of these areas or outside of the UK we will chip in with a  £10.00 discount on the plotter price in lieu of the free post.
