Hi,
I suck with RF and I'd like to ask for help.
I want to attach an external GPS antenna from my bin to a VK2828U7G5LF (
) module, so that I can mount it to another PCB that will land in some enclosure at some point.
I've desoldered the stock antenna already, so what is a good approach to attach coax for an external antenna?
Can I simply solder coax to the pad where the old antenna was, and the coax' shied to GND?
Is there special consideration required, maybe in order to match impedance?
The passive parts and LNA between antenna pad and the ublox G7020 can stay as-is, I presume?
Any RF magic or some sort of sacrifice required?
Thanks,
pit
