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


Outline.
  • It is the form memory type strait-wire (18cm) antenna of 1/4 wave
  • It is an antenna only for transmitters with the terminal of a 2mm screw formula.
  • Notification distance increases about ten percent from a helical formula.
  • What can be used is a transmitter (KTK-400, KT-400, KT-400D, KTL-400,KTLV-400,KTB-400, KTB-400D,KTB-500). It can be used for the transmitter of all with screw terminals.
Directions
  • It is used by thrusting into the screw terminal portion of a transmitter. Please perform the desorption of an antenna as carefully as possible.
  • Sensitivity becomes [ the direction formed perpendicularly ] good most.
