Ok,
Yes, I know for sure
There is no "Rf" cable.
The base station simply plugs into the ST1 bus in the instrument chain.
So, anywhere will do.
I don't think there is a range issue.
But, if you want a neat place to relocate the base station, you could put it into the spray hood area. There is already ST1 in there from the wind gauge.
A bit unrelated...
If you have a 49 then you have the metal framed chart table seat.
To get access to the autopilot, or any stuff under the chart table, you have to remove the chair, or you will squeeze yourself to death trying to get in there.
I have had this seat out many times, for access to the breaker panels, etc.
The seat was screwed to the floor with #12 wood screws.
What I did was install 5-16 /18 threaded inserts into the floor.
Now, I just have machine screws & washers, and the seat comes out in < 5 minutes.
If you try to remove & re-install the original wood screws more than 3 times, you will destroy the holes in the floor
I used Allen head machine screws. It's super-easy to get an Allen key in to remove or re-install the bolts
