PolarFlip — RH / LH Circular Phasing Box

PolarFlip is a precision phasing device that accepts two matched linear antenna inputs and produces four simultaneous outputs: ANT1 (linear), ANT2 (linear), RHCP (Right-Hand Circular), and LHCP (Left-Hand Circular). It is designed for HF low-band and NVIS receive systems where polarization behavior dictates signal strength and stability.

Key benefit:
Instant access to both hands of circular polarization — no relays, no switching delay, and both linear channels available for reference or diversity.

Main Features

  • Four simultaneous outputs: ANT1, ANT2, RHCP, LHCP
  • Transforms two linear antenna channels into both circular hands
  • Improves SNR in conditions with Faraday rotation or polarization mismatch
  • Low-loss hybrid network with high isolation between RH and LH
  • Compact and shack-friendly phasing enclosure

Applications

  • Low-band HF receiving (160 m to 30 m)
  • NVIS systems where ionospheric rotation causes fading
  • Diversity reception with linear channels plus both circular channels
  • Contest field stations, portable ops, and DXpeditions
