Just discovered this nifty device on the OCC Facebook site. It amplifies Wifi signals and feeds them into a router so that weak shore based stations an be accessed by all wifi device on board. Rogue Wave WiFi

Hi All
we are in the immediate market for WiFi antenna and on board router. I note this thread is now over five years old. Does anyone have any updateson equipment recommendations?
We spent the past two seasons in Spain and Portugal. With the sole exception of RCN Vigo, reception in marinas was non-existent - forget about when at anchor. We both resorted to using mobile data via our smartphones.
Any advice will be most appreciated.
thanks in advance
Alex
