218 & 218.1 Ground Plane (Monopole) Antennas 225-400MHz
For Air-Band Communications

These omnidirectional antennas have constant patterns and impedance over a greater bandwidth than a conventional ground plane or coaxial dipole antennas. This superiority makes them eminently suitable for use at base stations for mobile systems and particularly for ground to air communication services.
They are of rugged construction. Standard models are manufactured from aluminium. 
 

• Broad elevation radiation pattern provides superior coverage for ground to air links
• Designed to withstand the most severe weather conditions
• Robust design and construction
• Heavy-duty welded on radials
• Painted finish for additional weather protection
• Can be mounted to a horizontal surface (model 218) or to a mounting pole (model 218.1)
