These are direct replacement antennas for Spektrum SR6000t, SR6100AT, SR6110AT, and SR6200A among other brands such as Futaba, Flysky, and others. (Please check that your receiver antenna plugs in opposed to soldered to the receiver.) A .050" hex screwdriver is needed to take apart the receiver case to replace antenna.
This is for the two replacement antennas only (receiver not included). I've received 100% positive feedback on these OEM direct replacement antennas. Shipping is fast and FREE via USPS first class mail. Thanks for looking!
