RMILEC 400-470MHZ UHF Frequency Hopping LRS for JR Radios This LRS system is well made and perfectly fit JR radios like FF9 10C 8fg etc. for other radios, you must do some wiring work to get ppm, V+ and GND from your radio and the system will work.The new system is based on Ham band and neighbouring band from 400mhz-470mhz, with the frequency hopping technology and frequency sweeping technology ,you never need to worry about losing control of your precious plane. Have short range trouble? this LRS has a range beyond your imagination. with a bad antenna, you may still get 20km range in the air ,and with a super good 1/2 wave length one ,you can even get 60km in the air Advantages: 1. power: 1000mw--2200mw 2. control distance: 40KM--60KM 3. highly anti-interference
using this equipment , you can get a excellent control distance and add two chanels , up to 14 channels to receiver .
