I use the WaveRV marine antenna. Near metro, etc. areas I can get
adequate 'signal' 2-3 miles off the NE US coast. I have it mounted on
the stern rail ... seems to work better there.

You are height limited by the 15 ft USB cable are you not ?

There are obviously situations in a marina where height may be a
disadvantage but I've found that the higher the better if you are
trying to get above the nearby clutter and achieve some real distance.

My record is about 5 miles while actually underway, with the antenna
about 30 feet above the water. Last November I was solidly connected
for a month to an access point in Nags Head, NC while docked at a
marina 3 miles away on Roanoke Island.
