  • Description
The Diamond Antenna NR770HNMO is a great dual-band mobile antenna that offers a handy fold-over feature to get your rig into or through a low-clearance area without damaging or breaking off your antenna. Just pull up on the whip holder and lay it down.

The NR 770 series stands at just 38-1/2" tall, but still provides 3dBi gain on 2 meter, and 5.5 dBi gain on 70 centimeter. They're capable of handling up to 200 watts.

NR770HNMO Features

  • Fold-over design - great for areas with low overhead
  • NMO Connector
  • Dual Band - 2 meter / 440
