RadioLabs USB Marine WiFi, the one?
I’ve never heard of RadioLabs before, but maybe it’s come up with an excellent aid to onboard WiFi reception. The WaveRV Marine is an 22” 8dB omnidirectional 2.4 GHz antenna with a 400 mW WiFi radio built into its base. A 15’ USB cable moves data and power between the WaveRV and a down-below Windows, Mac, or even Linux computer. The unit is waterproof, fits a standard marine antenna mount, and costs $170 plus shipping. The fifteen foot power/data cable might be too short for some boats, but otherwise this looks like a good alternative to Wayne’s Way, etc. Here’s RadioLab’s WaveRV Marine page, and here’s a highly optimistic press release PDF. (Four mile range? I don’t think so.) By the way, I’m hoping to test this product.
