off at highway speeds, it could hit the ground and bounce back up into or
towards another vehicle. That outcome could be disastrous. I run a magnet
mount and don't really like it but I figure is shouldn't go too far since it
is attached at least by the coax. Not much security there but at least it
offers some. I have had a previous antenna flop over and bounced the tip off
the ground when traversing a gravel road. My goal is to get everything
external to be part of the vehicle. Currently the only mag-mount is for my
900MHz antenna which is small, at least it won't tip over. A sudden stop
might be a problem though.
I have a small piece of luggage that has a strap for attaching a briefcase
of another bag to it for rolling around. The strap with the buckle might go
around a luggage rack and suction device handle. The strap and buckles can
be purchased at some outdoor stores. I use to buy them at Kirkham's in Salt
Lake City when I lived there. I would then stitch everything together. Yep,
I can sew too.

I don't have any ideas yet but now I am on the hunt. I have been waffling
about getting a T2-301 for doing basically the same thing. I want one but I
have other items on my project list. I am slowly working on a GO-BOX which
currently has higher priority. If they show up as in stock I may loss my
self-control. Hmm, isn't self-control it's own reward?
Thanks again for sharing!
- I'd be worried too about anything suction cupped to the outside of a moving vehicle! Suction cupped to the inside with a little 'Hearsy Kiss' type magmount antenna would keep everything dry, no worries about water intrusion. Plus, the antenna would be mounted vertical atop a good ground plane, vs a lossy rubber duck at an angle.
I had to relocate my GPS for aircraft use, the AIO would lean against the side window... resting on a window sill. One small suction cup with a small hole on the attachment side for the antenna (non OEM) kept it against the window. The GPS unit would be looking at the horizon or lower. I removed it from the circuit board and mounted it 90 degrees to the circuit board, facing up. Plus, my case was a metal case so it had to be cut for the GPS antenna to 'see' the sky.
