Product Description

The Y6625D is ordered around the operating center frequency rather than from a short fixed suffix list. Within the 200–250 MHz tuning range, the five-element array provides 8.6 dBd gain for rail and other fixed directional links.

Defined operating window: Bandwidth is specified as 4 MHz at 1.5:1 VSWR and 8 MHz at 2:1 VSWR around the selected center.

Higher-gain rail option: Compared with the three-element Y6623 family, the Y6625D uses a 52-inch boom and tighter beam for more concentrated coverage.

Ideal applications:

  • Positive Train Control
  • Rail wayside systems
  • Center-frequency-specific fixed links
