Well, I'm glad you guys figured out what I meant, despite my lousy grammar and lack of proofreading.
I have my eye on this project for autonomous drone command & control, so operating the device inside a Faraday cage to prevent leaking a signal that might interfere with others would defeat my purposes.
I suppose the correct design would be to use two (one for the base station and one for the device) so that some other part of the RF spectrum could be used instead.
You could always try XBee. The XBee Pro modules are a bit expensive (~$50 each), but they can reach up to 15 miles or more, albeit at fairly low baud rates. The Pro-900 XSC ( https://www.sparkfun.com/products/11634 ) can stretch up to 28 miles with just its wire antenna. There's also LoRaWAN, which is even longer range but still low bandwidth and $$.
