BSL450XL6 Series (6 dBd UHF)

6 dBd UHF Base Station Antenna


The BSL450XL6 Series is a configurable 6 dBd UHF base station antenna with a 20° vertical beam across 406–512 MHz for fixed radio sites.

Key Features

  • Focuses coverage near the horizon with 6 dBd gain and a 20° beam.
  • Offers multiple tuned configurations across 406–512 MHz.
  • Handles up to 250 W for base-station or repeater equipment.
  • 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

BSL450XL6 Series provides tuned 406–512 MHz coverage for fixed UHF base station and repeater installations in the larger BSL mechanical format.

Frequency-Specific Selection: Each available configuration is tuned to a defined portion of the series range, allowing selection around the site’s assigned UHF channels.

Coverage Pattern: Its 6 dBd gain and 20° vertical beam concentrate coverage closer to the horizon for relatively level sites.

Outdoor Mechanical Package: A 1.5 in (3.81 cm) UV-inhibited fiberglass radome and 1.95 in (4.95 cm) epoxy-coated aluminum sleeve provide a larger mechanical format for exposed sites. The assembly carries a 125 mph (201 km/h) wind rating.

Power and Connection: The antenna handles up to 250 W and uses an N female RF connection. Compatible clamp-style mounting hardware is available for pole and mast installations.

Ideal Applications

  • 450 MHz fixed radio networks
  • UHF base station and repeater sites
  • Pole- and mast-mounted communications infrastructure

Example Model Configurations: BSL450XL6-A, BSL450XL6-B, BSL450XL6-C, BSL450XL6-D, BSL450XL6-E
