Some years ago, while at the Fl Lauderdale Boat Show, I bought a WiFi Booster which was advertised as being able to greatly increase the range you could receive a WiFi signal while aboard your boat. It was designed to mount on a stantion or better yet to be raised with a halyard high above deck.
I have no idea how well the thing works as I never even got to try using it. But it SHOULD work as I think I paid a couple hundred bucks for the thing.
Since I no longer have a boat I no longer have use for it. If anyone here would like to have it it’s yours for the asking. Actually it’s yours for the shipping.
