We use a dedicated VHF/AIS antenna to transmit and receive..

Tram Combo VHF/GPS 39 inch Antenna

This is what we used with our Vesper 8000 transceiver. Total cost less than $600, compatible with NMEA 2K as well as NMEA 0183. Using it with a pair of Raymarine E-120s. Works a charm.

Regarding the antenna: The boat originally came with an AIS from West Marine that transmitted through a small sailboat antenna. While the AIS was good, reception was poor (assuming transmitting was also) because of the small antenna. The AIS wasn't reprogramable as WM doesn't support it any more (thanks WM I don't support you either). In the process of redoing the VHF antenna and the AIS, I decided to try running the VHF through the AIS unit to a 17' Shakespeare antenna. Very happy with the results and no loss of performance with either unit. The larger antenna gives much better reception and I assume transmission of the AIS information. Where this really makes a difference is traveling in winding rivers and channels. I can now see tugs pushing barges miles in advance of meeting them. If you travel inland waters with tall trees, buildings, or other land masses, gain and height of the antenna makes a big difference.

We have a dedicated GPS antenna.

Mind me asking where you scored that deal? This is what I plan to add.

Port Orchard iirc. I have been thinking of connecting with them this fall based on your prior recommendation.

Could you explain why you do this please? What's the advantage over using the transponder to send and receive? (I get the 'at night' bit but presume this is not the reason for using the SH receiver instead of the transponder)

thanks

We went the same route, and it's working perfectly.
