A5003S-OBH Bulkhead Mount Antenna

5 GHz Bulkhead Mount Antenna


The RadioLinx A5003S-OBH Bulkhead Mount Antenna is a rugged style antenna and excellent for outdoor or indoor industrial applications. The design features field diversity with both vertical and horizontal polarization components. This provides the antenna diversity, frequency agility, low visibility, wide bandwidth, and a low angle radiation pattern that is superior to traditional gain antennas in most applications.

Features and Benefits

  • Superior performance
  • Excellent for voice to telemetry applications
  • Permanent mounting for high-risk applications such as metering where antennas must resist vandalism and achieve economical mounting
  • No groundplane is required for proper operation
  • Field diversity means that the antenna is simultaneously sensitive to both electric and magnetic fields of signal, like having two antennas. Field diversity makes the antenna resistant to the picket fence fading and multipath nulls that are found in urban operation and undulating mobile environments
  • Low Profile design provides watertight seal
  • Lightweight fiberglass radome
  • All weather operation


All antennas have been tested for compatibility with RadioLinx products. Please see our Antenna Selection Guide to assist you in choosing the best antenna for your application.
