Of course, environment and installation is key to getting good range. I have no experience with the GI-100 so I wouldn’t know as to range. But I would imagine that 1 mile is not unrealistic with a good installation and proper environment.
If range is problem where you are because of circumstance, I would look into having the transmitter installed at a friend’s house or business where the environment would be more favorable for Part 15 AM and use Barix boxes and the internet to feed the transmitter.
I have a friend who has a business in town that has offered to host my transmitter. In his case, the building he owns has an all metal roof so the roof can act as one giant ground plane for the TX and there are no trees nearby. I expect I can probably get 2 miles with that installation. He will let me have the location for free if I mention his business every hour. No problem.
The GI-100/1000 with the antenna and interconnect board would be $705.00 plus shipping.
