The multisector antenna has been recently developed by SVP. It consists of 4 sector panel antennas, which have 90º wide beam to provide 360º coverage, and an up-down antenna.
Among other applications, this multi-sector antenna is very useful to receive/transmit signals from a moving vehicle, such as a helicpter. When the helicopter is far a sector antenna will receive the signal and if it is near the signal will be received by the up-down antenna.Five down-converters are located inside the antenna so, the received signal is converted to the UHF band. The outputs of the antenna are connected the to a diversity 6 receiver. No external down-converters are needed.As shown on the photos below, this multisector antenna is a very compact, robust and easy to install solution.
