I have personal experience with respect to this topic. Putting a wi-fi
antenna at the masthead is the WRONG thing to do. You don't want it high
up. You want it low down. It gets better reception low. The signals seem
to be stronger low. Mount a good amplified antenna at deck level for the
best reception. No need to worry about long lengths of co-ax at all.

Here's a good antenna that works well and is priced reasonably.

If your antenna is vertically polarized you could see a 3 dB increase in
signal if it placed over a conducting ground plane such as salt water.
This is explained by the theory of images, which in effect doubles the
antenna gain toward the horizon. If the antenna is horizontally polarized
the radiation pattern become directed more skyward and there is an
associated decrease in gain toward the horizon. Wilbur, you have a keen
sense of observation.


Thanks. I can't help but be brilliant.

From the spec sheet: http://www.radiolabs.com/downloads/WaveRV.pdf

vertical beamwidth - 35 degrees
horizontal beamwidth - 360 degrees.
