gps antenna- mix and match brands??
I have just upgraded my Furuno GPS to a Garmin GPSMAP, I was hoping to use the same antenna (a Furuno one) as it is mounted nicely on my A-Frame.
The Furuno GPS unit worked fine and got satelites usually within seconds.
The GPS map I could not get to pick up a signal, so I tried just holding the Garmin antenna which then got a signal perfectly.
When I plugged it back into the Furuno one, it kept moaning that the antenna length had been shortened??
The Furuno is on about 5m of coaxial which runs under the deck to the antenna, which has an additional whip on the top of it. The garmin is on about 2 feet of coax and just being held by me!!
I'd like to use the Furuno one if possible, but if not I guess I can remove it and create a join in the coax to mount the garmin one (as I will need the length running under the deck) but then I am not sure how badly this will degrade the signal, or even if the coax is the problem?
