Re: Antenna

[Al Grant]

Thanks Gary,

It looks like I will be investing in a new GPS that supports as many

Form factor ideally suitable for Rpi - maybe USB interface with 10Hz
update rate.

Antenna to match magnetic mount with active.

Does this provide enough info for a recommendation for both?

Cheers

AL
