I have tested my stock Futaba 6ex 2.4ghz out to 1.75 miles with no problems,
but it probably can not match the video range. But as a general rule Futaba transmitters are twice the range of Spektrum ones.
I hope this can save other people from searching the internet for hours on end for the best deal.
1) Birds Eye View Rc.com is a Chinese company not US
2) 1.2 GHz band is emergency services/law enforcement frequency band in the US except for the 1280 MHz channel
3) Requires an FCC Technicians license to run in the US at that output level
4) the patch antenna is really a 1.2 GHz not a 1.3 GHz antenna but it does work at 1280 MHz
other than that you got it
Birds Eye View Rc ships from the us and that was my 4th point! I gurantee that you don't have to have a technicians license to operate it and the bob tx rx is crap!!!!! Trust me after hours of surfing and reading this is the best system.
Last I checked Colorado was still in the United States and any RFcommunications fall under FCC guidelines. The 23cm (1240-1300MHz) band is under the Amateur Radio "Ham" band allocation, and as such requires at least a Technician class license to legally operate. Check the attached PDF for a complete listing of these bands and their required licensing.
