2 GPS antennas (any Interference)

[mildew2]

I bought a backup GPS for my 2120. The main unit I have has an external antenna mounted on the roof. The backup also has an external antenna that I will be mounting on the roof. One is Lowrance the other Garmin. Will I get any interference between the two? Or lose any accuracy? Can I mount them close to each other? Thanks

I have two one garmin, one raymarine, both work fine. Have never had an interference problem.

No interference possible, a GPS is a RECEIVER, not a transmitter.

Mount as many as you want.

I have a Lowrance and a Garmin about 6" apart on the roof of my 2120. No issues at all. As was said before, they are a receiver so it should not matter as long as one is not blocking the signal from the other.

I agree with Bryan 2530.
