I am toying with the idea of getting an aftermarket Gilsson antenna for
my GPSMAP 396 from www.gpsgeek.com. Has anyone had any expereince with
Gilsson antennas for aviation use? Supposedly they have better gain
than the Garmin units.

Hell it's on sale for $20. Try it out, if no improvement dump it on eBay,
maybe make a couple of bucks.
