Range of 3DR Link

Posted by Simon Faulkner on May 4, 2014 at 7:56am

What sort of range are people getting from the Stock Aerials on the 3DR Radios at 433 MHz?

I am currently running a clone board at each end but was only able to get around 50M range when flying yesterday even when I oriented the aerial at 90 degrees to the vehicle for maximum signal strength.

How best to increase the range?

Switch to genuine 3DR radio

Change the aerials

Software settings

    If you're using ground module with integrated USB connector (plugged directly to PC) - do not expect nothing more...

    Check also stock antenna - sometime chineese clones are shipped with 2.4GHz antennas.

    You should have over 1.5km with simple DIY dipole antenna (that's what I have with my homemade SiK/HM-TRP modems).
