Overview
The CPAA-18 is the flagship of receiving antennas due to its improved reception performance. Circular polarization, compared to traditional linear polarization, performs much better in non-line of sight situations and mainly in situations where the transmitter antenna can be
Randomly oriented in the horizontal or vertical position. Furthermore, the extremely low noise, high quality built-in amplifier is ideal for situations where long cables with high attenuation must compensate or where the signal strength is too weak.
