But one aspect of the unit has bothered me since we put the whole thing together and that was the waterproof electrical box that everything was mounted to. It did work fine and kept the unit dry, but we just were not crazy about how it looked. People walking down the docks would stare for a while before asking what in the world it was. The gray plastic box was just not aesthetically pleasing so I started considering other options that would be easy and inexpensive and give us some options for mounting. On the sailboat we simply tied it up in the rigging and could remove it if sailing or the weather was really bad. On the trawler we wanted a more permanent mounting, but it too had to be weatherproof since the adapter is very moisture sensitive. Ever time I wandered the local building supply I considered different approaches. I finally decided on using a short piece of PVC pipe with sealed end caps top and bottom.
Making the case was as easy as the original, drilling a hole in the top cap to accept the antenna and two holes in the bottom cap. One would be for the USB cable to pass through and the other would be to accept the rail mount that we would use to mount the entire unit as high up as we could get it on the bimini frame. The mount is a typical rail mount used for antennas for a VHF or GPS. It turned out to be a perfect solution. The antenna, cable pass through and rail mount were all sealed with marine silicone sealant because all of the parts are plastic and silicone is the best sealant to use, IMO. I chose the four inch pipe, not because the parts are that large but because the antenna and USB cable connections stick out from the sides of the adapter and I did not want to jamb everything in tight. Once everything was tucked into the pipe, both ends were sealed with silicone and the caps pushed on tightly being careful not to pinch and cables. We also decided to replace the USB cable from the short cable that comes with the unit, to a fifteen foot cable with USB on one end and a mini-plug like those used for camera connections, on the other. The mini-plug is the same type that plugs into the adapter. This kept any extensions we might want to add inside the boat and out of the weather. We used a plastic cable wrap on the USB cable that would be exposed to UV to protect it.
Once everything was assembled and the unit mounted we went from a single signal from the laptop internal connection to about ten available connection. Most of these were security enabled requiring a password or key to connect, but three or four were open connections and the marina connection went from barely connect to a strong connection. I am sure we will still get the puzzled looks and "what is that" but at least now it looks acceptable and should be well protected from the elements. Now we just can't wait to use it while we are cruising
