Dragon Link Receiver Antenna SMA Description:This is a High Performance RX antenna for the Dragon Link receiver with 6 inch semi Rigid cable for crash protection.This super high performance antenna is for use with any Dragon Link receiver. It has a very flexible 6 inch coax extension, SMA Male connector, and is ideal for use in Copters and Small planes. The coax can be coiled, bent, or routed any way you like without affecting performance. Plastic tubes are included to keep the wire elements straight, but are flexible and designed to bend in case of a hard landing or crash.For maximum performance and long range of 10 KM or more, both antenna wire elements should be straight and vertical, and mounted away from Video Transmitters, Cameras, and other noise producing devices.For COPTERS and small FPV planes. The top element should be straight, while the bottom element can hang free, or be routed flat along the copter body. This will still give you really good performance, and still give you longer range any copter is capable of flying.This antenna should NEVER be used in a V-configuration!This antenna is designed to be durable, but for planes that take a lot of abuse, and tend to flip on landing, you may coat the little transformer in the middle with expoxy glue if you like to prevent this part from being easily damaged.Dragon Link Receiver Antenna SMA Specifications:Element Length 15 CM EachFrequency 420-440 MHZDragon Link Receiver Antenna SMA Includes:1 x Dragon Link Receiver Antenna SMA male connector2 x tubes4 x nylon cable ties 3-1/2"Dragon Link Receiver Antenna SMA Pictures:[img-4896-left-thickbox_default]
