Unique design features of the Q20-5 include a multilayer polarizing grid integrated into the radome, which allows the vertical, linear dipole elements to receive RHCP signals without loss in efficiency. For maximum strength and minimal RF impact, the radome has been fabricated from a quartz-based material and is impact and erosion resistant.
The Q20-5 is provided with a waveguide interface to minimize signal losses associated with coaxial transmission lines.
