SMA Monopole
Experimental Aircraft Only
The UC333 is a non-certified transponder antenna for experimental aircraft only, which includes most UAS.
Plug and Play
Simply connect the UC333 SMA monopole antenna to the transponder (e.g. using UC323 SMA-to-SMA cable) and it's ready to go.
World's Lightest & Smallest Transponder Antenna
At 7 grams and just over 2 inches long, this is the lightest and smallest transponder antenna in the world. Designed specifically for UAS, this little antenna outperforms antennas ten times its size.
The UC333 is a non-certified transponder antenna for experimental aircraft, specifically targeting small unmanned aircraft (sUAS).
