Bloody Quick reply from New Zealand!
You don't need any bits other than the transponder itself and a VHF antenna
Here's the options:
1. WatchMate-850 - has everything you need for a dedicated screen-based low-power consumption
AIS transponder. If you install it with a view of the sky (say under a canvas
dodger) then it will work fine with it's built-in GPS antenna
. If you install it below, then you'll need one of our external GPS antennas.
2. WatchMate-Vision - also has everything needed for a dedicated color touchscreen AIS transponder with WiFi
. Same thing for the GPS antenna. No need for an external one if mounted in a place with a view of the sky. If down below, then you need our external GPS antenna. WiFi allows you to also use it with a tablet or smart phone
3. XB-8000 - comes with the external GPS antenna because these are almost always installed below in a locker somewhere. Needs some sort of display system such as a chart plotter. Has WiFi so you can use a tablet or smart phone
apps. Has NMEA-0183 and NMEA-2000 for interfacing to MFD's and plotters.
All of these require a VHF
antenna. The simplest case is a dedicated VHF antenna mounted on a stern rail or better yet a bit higher on an arch, solar
array, radar pole, etc. The antenna should be mounted in "clear air" as far away as possible from other antennas and parallel metal structures like masts and rigging
You can optionally share an existing VHF antenna, such as at the mast head
, by using one of our splitters (SP160). This is often the easiest way to install any of the transponders because it doesn't require another VHF antenna and the splitter acts as a junction box too. Our splitter is unique because others impose significant signal loss, but ours actually has signal gain due to its built-in amplification. The result is an increase in AIS receive range.
So... you need the transponder and a VHF antenna. You may need an external GPS antenna depending on where you mount the unit (not needed to buy with the XB-8000 because it comes with it). Optional: you can eliminate the VHF antenna and use a splitter instead.
All of our transponders are flexible and can be integrated with other equipment
, like MFD's, instruments, plotter, radars, VHF radios, etc. but none of that is required.
To install you might need a few bits of wire and a fuse holder and/or available circuit breaker.
