Yes I was going to mention it was a supply & demand situation that is not so apparent in Europe.
In the Caribbean there are many AP's (access points) without security who's providers generally don't mind you connecting to them. Its also expected that most marina's provide some sort of wireless Internet access. I guess the latter is no different in the UK, but have not sailed there for ten years.
WiFi-Stock in the UK supplied all my equipment but as well as Bullet you will also need antenna (aerial) & POE (power injector) which should take you well over £50.
Let us know if you require any more help.
BTW the cable from the Bullet is a LAN Cat 5e (twisted pair) cable just carrying TCP/IP data like the cable that connected your PC to router before wireless, & can be up to 300 feet long with no loss of data. It is not a coaxial one & carries no RF - all the radio stuff happens at the Bullet/Antenna.
Its a matter of preference but I have my Bullet/Antenna mounted on the pushpit about 7 feet above deck - see post #14 (page 2) on this thread. 13 metres of LAN cable feed through the deck & a hidden route to the chart table where I have located the POE adapter
to feed power from DC power sockets I have available on control panel. I can then use further short LAN cable direct to my laptop or feed a WiFi router within my boat for wireless access.
This means my installation is permanent, no hoisting up & down mast with attendant wear & tear. No worries about using tall antenna's at top of mast & easy maintenance if necessary. Using the boats 12 volt system I don't have to worry about volt drop over the longer length of cable either, although I'm told the Bullet works at full power down to 10.5 volts at the device end of the LAN cable.
