Light Beam – LB-20M


  • Manufactured with thick wall fiberglass tubes as spreaders.
  • Spreaders are fastened to heavy 1/4 inch aluminum end-plate hubs using stainless steel self-locking fasteners

Like the Light Beam Plus Antenna series, Light Beam series antennas are

  • very strong and durable
  • have the same Radio Frequency performance as the Light Beam Plus antenna series
  • just as compact – ideal for locations with limited space!

With low visual impact, the Light Beam Antenna is an economical choice for those who desire a high-performance solution and do not have as great a need for a “stealth” installation.
