... My challenge is to get the signal not only out of the boat, but down to my laptop, wirelessly. I can do one or the other brilliantly. So far I haven't done both in one box. So don't. Keep a cheap wireless AP in the cabin in your boat, run UTP ethernet cable to the masthead device, along with the 12V, presuming you were already running that. The requirement then isn't whether the high-gain kit can send a usable omni signal too, but whether it has an ethernet interface. So, as the computer expert, leaving the challenge of antennas to me, what (12 V input, thank you very much) device does what I need? I'll figure out how to antenna it and elements-protect it. You might have a look at some of the many websites about building wireless community networks. There's even a book of that title on O'Reilly press these days. These places will be where pushing the limits or 802.11 gear is routinely discussed. There are links to some such networks at: http://en.wikipedia.org/wiki/Wireless_community_network For what you are proposing, as I understand it, two antennas/interfaces seems to be the go. If you consider they are doing different jobs, it makes sense. It's only a pity the masthead device is USB: if it were ethernet, all you'd need would be an inexpensive wireless AP that is also an ethernet switch. As a bonus, any non-wireless computer you subsequently installed onboard would have a wired switch port to connect directly to. Also note that you're not restricted to devices that come with supply units that can run off 12V: most devices like this have extremely modest demands and dc-to-dc supplies of various capabilities are readily available. --Damian |
