Non-Directional Antennas

Model 504, 506, 540, 545F/T, 550 and 613

  • Dual take-off angle provides optimum gain for short-, medium, and long-range circuits
  • Easy and rapid installation
  • Lightweight and small size
  • Horizontally polarised to eliminate ground losses
  • Transportable Tactical (T) and Fixed (F) versions available
  • Rugged construction


The Model 504 family of rosette dipole log periodic antennas is designed to provide high gain, high front-to-back ratio, and steerable performance in a compact area.

The Model 506 family of conical monopole antennas utilizes a new class of radiating structure.

The Model 540 is a horizontally polarized, omnidirectional log- periodic antenna embodying a radical new design, and having remarkably high omnidirectional power gain.

The Model 545T transportable dual take-off angle antenna provides the features most desired in a tactical antenna required to communicate over any range at any azimuth.

The Model 550 is an excellent choice for omni-directional HF communications, where both ground wave and skywave coverage are required.

The Model 613 is a truly broadband dipole antenna with excellent performance over short- and medium-range circuits.
