Assembly formula small pocket Yagi Antenna
NY-399B


Outline
  • The NY-399B is three sectional Yagi Antenna 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.
  • A photograph is in the state equipped with the three channel discovery device (KRS-300,KRS-300S) for tracking .
  • A photograph equips with a micro three channel receiver (KUR-400). It can be heard in the place which the transmitter with which even about 200m was able to be heard left about 300m.
  • 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, such as KKZ-100, are connected in coaxial code.
