Assembly formula small pocket Yagi Antenna with Attenuator
NY-399C


Outline
  • The NY-399C is three sectional Yagi Antenna with built in attenuator and convenient for carrying .
  • It excels in directivity and might is demonstrated to tracking of the transmitter which moves etc.
  • Since the antenna itself has the profit of 6dbs, compared with an ordinary whip antenna, a receivable distance is prolonged about 1.5 times.
  • The attenuator of -30dbs of a switch change is built in. It is very convenient when using for a tracking discovery device.
  • A photograph is in the state equipped with the three channel discovery device(KUR-400) for tracking .
  • It can use also for a common receiver. (399Mhz +- 2Mhz)
Directions
  • It is completion if the element of six directions is thrust. It can be used if a receiver is attached in the connector of a wooden handle portion.
  • Although a connector is BNC type, it is connected using a RCA type conversion connector.
  • Larger receivers are connected in coaxial code.
