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.
Have a great summer.

Ok here is the explanation.

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.

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.

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.

Eric,

You will loose a lot of distance with VHF by mounting it low.

Our AIS receiver which currently shares the AM/FM antenna on the main mast.
The AM/FM antenna on SM #387 is identical to the VHF antenna. I used a BNC
"T" to split the antenna wire for the radio and the AIS receiver. I have
noticed no problems with either the radio or the AIS receiver. This will not

work for a AIS transponder, but, I am considering buying a small antenna for

the radio, placing it inside the radio drawer. This will leave the AM/FM
antenna exclusively for the AIS transponder.

On SM #387, the triadic stay is rigged with insulators and the coax cable
from the stay terminates in a coil behind the radio/Hydra drawer. I think it

is too long for proper VHF (300mhtz = 1.6 feet of antenna for one-half of
the signal's total wavelength), but possibly could be used to receive AM/FM,

freeing up the Main Mast AM/FM antenna for your transponder.

Let me know what you do.

Best,

Bill

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.

Eric & Richard,

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.

On SM #387, the triadic stay is rigged with insulators and the coax cable
from the stay terminates in a coil behind the radio/Hydra drawer. I think it

is too long for proper VHF (300mhtz = 1.6 feet of antenna for one-half of
the signal's total wavelength), but possibly could be used to receive AM/FM,

freeing up the Main Mast AM/FM antenna for your transponder.

Let me know what you do.

Hi,
I just changed out my AIS receive only for a AIS Transceiver.
We are receiving ships up to 120 miles away.
However I am wondering where I can mount the GPS antenna on my Amel Super
Maramu #376 Kimberlite.

One side of the stern rail has the HF antenna the other the ships GPS.
The mizzen top has the navtex antenna, a seeme transponder and the AIS
receive antenna.

Any Ideas as to where to mount the antenna.

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.
Your thoughts.

Bill,

I already had an ais receive only antenna mounted on the top of the mizzen
dedicated to the AIS only.



I have now purchased an AIS transceiver and my question was where do I mount
the GPS dome for the new AIS unit?



Thanks for all of your work, photos and advice on our boats.

Eric,

You will loose a lot of distance with VHF by mounting it low.

Our AIS receiver which currently shares the AM/FM antenna on the main mast.
The AM/FM antenna on SM #387 is identical to the VHF antenna. I used a BNC
"T" to split the antenna wire for the radio and the AIS receiver. I have
noticed no problems with either the radio or the AIS receiver. This will not
work for a AIS transponder, but, I am considering buying a small antenna for
the radio, placing it inside the radio drawer. This will leave the AM/FM
antenna exclusively for the AIS transponder.
