1/4 wave of screw formula straight-wire antenna
ASR-399


Outline
  • A wearing portion is 1/4 wave of RCA type form memory type strait-wire (17cm) antenna.
  • It is an antenna only for a transmitter and receivers with a RCA type terminal. @@
  • Sensitivity becomes good about ten percent from a helical formula.
  • It becomes a receiver (KUR-400, KKZ-100), scramble receiver (SCR-100R), a remote control receiver (KRT-400R), and a remote control transmitter (KRT-400T) and tracking receiver (KRS-300, KRS-300S) that it can use.
Directions
  • The desorption of an antenna should have both sides for a root portion with a finger, and please perform them as carefully as possible, turning to right and left little by little slowly.
  • Sensitivity becomes [ the direction formed perpendicularly ] good most.
