BSL150XL3 Series (3 dBd VHF)

3 dBd VHF Base Station Antenna


The BSL150XL3 Series combines 3 dBd VHF gain with six tuned 6 MHz configurations across 144–174 MHz for fixed radio sites.

Key Features

  • Focuses VHF coverage with 3 dBd and a 40° vertical beam.
  • Matches assigned channels with six tuned 6 MHz configurations.
  • 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 BSLMNT2 hardware.

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

Product Description

The BSL150XL3 Series gives fixed VHF sites 3 dBd gain across six tuned configurations spanning 144–174 MHz, packaged in the larger BSL mechanical format.

Tuned VHF Selection: Six model configurations divide the series into defined 6 MHz operating segments, allowing selection around the required VHF channels.

Focused Coverage Pattern: The 40° vertical beam concentrates coverage more tightly than a unity-gain pattern while retaining omnidirectional service around the antenna.

Larger Outdoor Construction: A 1.5 in (3.81 cm) UV-inhibited fiberglass radome and 1.95 in (4.95 cm) epoxy-coated aluminum sleeve carry a 125 mph (201 km/h) wind rating.

Power and Mounting: The N female-fed antenna handles up to 250 W, and the optional BSLMNT2 kit supports compatible pole and mast installations.

Ideal Applications

  • 144–174 MHz VHF networks
  • VHF base station and repeater sites
  • Exposed pole- and mast-mounted infrastructure

Example Model Configurations: BSL150XL3-A, BSL150XL3-B, BSL150XL3-BC, BSL150XL3-C, BSL150XL3-D, BSL150XL3-E
