They tell me that it will have a 245 nautical mile range- The national park is very interested in my project. To pick up the helis over my house the antenna needs line of sight that's why the ones at the airport only pick up higher ones- that will change with my station.
It's 1.09 GHz, so it's not actually line-of-sight limited as that will penetrate tree tops, etc. This is especially true if you can mount your antenna as high as possible and hopefully you got the filter too to reduce other interference. Hopefully you get a wider range than line of sight. The best system is if you can put the Antenna, Filter and a pre-amplifer all near the antenna and then run the rest down to your receiver.
What did the National Park Service tell you about their interest in the helicopters?
