Do not use the antenna any longer, and would like to use the coax to mount a WiFi antenna to run to my onboard laptop. My goal is better distances to AP. Anyone done something like this successfully. My laptop has both PC Card slots and available USB 2.0 ports. I can find numerous claims on the internet, but would prefer to find something that is a proven solution. Thanks Pete I currently use a USB WiFi amplified antenna hoisted on a flag halyard about 20 ft. above the deck. It certainly gives me an improved signal over the laptop's built in antenna located about 2 ft. above the water.. I did, however, find that there is a practical limit to the length of USB cable that can be used without some sort of amplifier in either the line or the antenna. Cheers, Bruce (bruceinbangkokatgmaildotcom) Yes, the USB spec says 5m MAX. After that you need to go through a hub. 5m USB extender cables are basically a 5m lead with a single port hub on the end. You can cascade up to 4 hubs if everything fully meets the spec which limits you to an absolute max of 25 metres end to end. Shorter *will* be better ;-) Otherwise there are two part USB extenders that use Cat5 UTP cable for the link and can go *much* further but they aren't cheap. Might be worth it rather than the aggro Skip Gundlach had with his public wifi - masthead access point -(ethernet)- local WiFi router lashup when he was trying to avoid wires to the PC. -- Ian Malcolm.
