BSDB18U8 (Dual-Band 800/1900 MHz)

Dual-Band 800/1900 MHz Base Station Antenna


The BSDB18U8 combines 825–896 MHz and 1850–1990 MHz coverage through one compact omnidirectional base station antenna.

Key Features

  • Combines two separated frequency ranges on one RF path.
  • Provides 3 dB gain with a 50° vertical beam.
  • Handles up to 250 W through a standard N-female connection.
  • Helps reduce intermodulation with welded and soldered copper-alloy elements.
  • Installs on poles or masts with optional BSMNT2 hardware.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

Two Frequency Ranges. One RF Connection.

The BSDB18U8 combines 825–896 MHz and 1850–1990 MHz operation in one omnidirectional antenna for fixed sites that use both frequency ranges.

Dual-Band Site Coverage: One N female-fed RF path covers both the 800 MHz and 1.9 GHz ranges, simplifying the antenna connection for compatible dual-band equipment.

Compact Omnidirectional Pattern: The 18 in (46 cm) housing is specified at 3 dB gain with a 50° vertical beam around the site.

Power Handling: A 250 W maximum rating accommodates compatible base station and repeater radios across both operating ranges.

Outdoor Mechanical Design: UV-inhibited fiberglass and an epoxy-coated aluminum sleeve carry a 125 mph (201 km/h) wind rating; the optional BSMNT2 kit supports mast mounting.

Ideal Applications

  • Dual-band fixed radio sites
  • 800 MHz and 1.9 GHz infrastructure
  • Omnidirectional repeater installations
