Eric have you thought about putting it on your port aft rail, or under the dodger? We find that our secondary GPS a hand held works well using its internal antenna as well as an external.

VHF is line of sight and rarely bounces. Mounting at the top of the main mast gives you around 10 miles further reach than mounting on a rail. The "range gained" formula is: 1.17 times the square root of the additional height in feet = additional range in nautical miles. The horizon while standing on the deck is 3.5 miles...from the top of the mast it is 10 miles. If you want to maximize being seen and seeing others, go up. GPS does not need height and will work OK under a dodger. Bill s/v BeBe, SM2k, #387 --- In amelyachtowners@..., kimberlite <kimberlite@...> wrote:

We too use an antenna on top of the mast using a spliter VHF/GPS and get very good contacts with major ships with our receive only unit. AIS is a very good safety device. We prefer using a stand alone display unit as there can be to much clutter on the Furuno radar/plotter in T-stroms.

Any chance you could use your current GPS signal and feed it to the AIS? Not sure why you'd have to have a dedicated GPS for the AIS. I don't see why you can't use your VHF antenna as well, unless the AIS transponder interferes with radio transmission...haven't looked into it, but seems like you could have the AIS transponder disabled whenever you are keying the mic.

I have a single GPS that feeds the Radio, AIS, and Computer (CAP'N program). Still don't see why your current GPS can't talk to the AIS. I do have two other GPS for backup, but not necessary for all three receivers.

Kent,
I already have a dedicated VHF antenna mounted on the mizzen from my receive only Ais which I replaced with the ACR transceiver. Unfortunately a separate gps is required with the transceiver by law !!. secondly there is no nmea input on the unit for the ships gps input. I have looked at many units hoping to use the ships GPS however I did not find one. Fair Winds Eric Amel Super Maramu #376 Kimberlite _____ From: amelyachtowners@...

The AIS B is required to have its own GPS since the boat it is mounted on might not have a GPS. The GPS dome does NOT transmit it locates my boat and sends it out vis the VHF antenna that I had originally installed for my AIS receive only unit. The AIS (by nasa) receive only used my ships gps to locate where I was in reference to the transmitted location of other ships. I hopes that explains the AIS issue.

Got it. Thanks. I guess they figure if it's on a GPS sending signal to multiple instruments it might not be as accurate??? Go figure.
