I don't know about anyone else but I can zoom out and view strikes anywhere in the world. Your location should be set automatically since the system that is installed has a GPS receiver. The alarm zone is around your location. You can't change the location on purpose.
The location is NOT set by the GPS. It's what they put in their system when you did the paperwork. I got access to the GE stuff prior to install because they had some delays on their end. It is pretty much centered on my location, but not really. It's close to my address, but not what the GPS gives. My yard's big enough that I can discern the difference between backyard where the GPS is, and the street.
On another note, the antenna was pretty much in pieces when I got it. They didn't use pvc cement to assemble it. I did.
And, yes I know the third leg of the mount is up instead of down. Not much weight to it, and there's an electrical panel on the other side of the wall where it would end up if it were down. Bottom of stroke antenna is 15 feet above ground and clears peak of roof.
They didn't say to - or not to - do it, but stroke and GPS coax goes to ground block bonded to local ground - 20 foot rod into water table, and shed electrical ground before going to their receiver. Center conductor to shield for stroke antenna has about 80 mv of 60 hz (clean sine) on it - probably from the 23 Kv primary out front, along with the assortment of HF, AM, and atmospherics on it, so pretty clean.
