Zaxcom’s BlueFin is an aerodynamic 8dB high gain directional antenna for use between the frequencies of 500 and 750 MHz. It provides a low VSWR for use as a receiving or transmitting antenna. The BlueFin supplies 8dB of forward gain and attenuates interfering signals that are coming from directions greater than 45 degrees off the front of the antenna. The cut-outs for wind make the BlueFin perfect for exterior locations
