Product Description

The Y3345D occupies the middle ground in the 406–512 MHz family: more gain and a tighter beam than the three-element Y3343, without the longer boom of the seven-element Y3347. Each suffix is tuned to a defined UHF block.

Five-element pattern: The antenna provides 8.8 dBd gain, 18 dB front-to-back ratio, and a 60° horizontal beam.

Mast installation: A direct N-female connector and 125 mph wind rating support permanent fixed-site use.

Ideal applications:

  • UHF base and repeater sites
  • Fixed directional LMR links

Example Model Configurations: Y3345D-A, Y3345D-B, Y3345D-C, Y3345D-D, Y3345D-E
