Default distance between vhf and gps antenna

How far should I mount my gps antenna (garmin 180) from my 8 foot Shakespeare vhf antenna on my T-top to prevent interferance?
Options are:
1. about 12 inches (preferred)
2. about 5 feet

Thanks

Mine is about 3' away. No interference problems that I can tell.

Mine are within three foot of each other. Keep in mind that the GPS is only a reciever. Most of the time the VHF is a reciever, too. Only when you talk would there be any chance of interference. I wouldn't hesitate to put them as close as your need.

Hey Mumble:

Is it warm enough yet by you to use that nice boat? My new one is still being rigged.

The one for my Garmin 2010 is 14" from the base of my DIGITAL 8' VHF antenna, and the FURUNO GPS antenna is on the other side of my hard top (about 4' away).

Never have I seen/heard any interference on the GPS even while transmitting on the VHF.

I have seen the radar have an effect on the GPS, though!

TRAFFICLAWYER...snow on the ground today. I will get the boat out of storage tomorrow and try to hit the water on Sunday. I have a few details to take care of. Get some of that heat up here!

This came up on a previous post. If you have radar, mount your GPS below the 'beam' from your radar.
