In Stock Betso Cpaa-18 Circular Polarized Active Antenna ~ Rare Item [18LADt5S]

The CPAA-18 is the flagship of receiver antennas because of its enhanced receiving performance. Circular polarization, compared to traditional linear polarization, has much better performance in non-line-of-sight situations and mainly in situations, where transmitter antenna can be randomly oriented in the horizontal or vertical position. Additionally the inbuilt, high quality, extremely low noise amplifier, is ideal for situations where long cables with high attenuation have to be compensated or where signal strength is too weak.

Features

• Highly efficient input filters for removing
  unwanted RF spectrum
• Easy gain setting with automatic last set gain storing
• Brightness of LED display can be automatically adjusted according to ambient light
• Display can be completely turned off with ability to show preset gain value upon button request

Circular Polarization Benefits

The main advantage of the receiver antenna with circular polarization is its orientation independence which is independent of the orientation of the transmitter antenna. In traditional linear polarized systems, when antennas are not aligned, there is a significant link performance degradation, which can lead to link losses -> dropouts.

On the other hand when the receiver antenna with circular polarization is used, this problem almost does not exist. Moreover, the link performance is even better in adverse weather conditions or in environments with a lot of obstructions, which are effects that cause signal polarization displacements.

Excellent RF parameters

What is unique about CPAA-18 is its excellent RF parameters.
Voltage Standing Wave Ratio of less than 1.2 ensures great signal power reception. Very high Third-order Intercept Point IP3 >34 dBm providing great linearity and finally industry leading ultra low noise amplifier IC with noise figure 0.75 dB.
