This new version of PA0NHC MiniWhip Antenna has these features.New version, using modern BF998 and BCX54 semi conductors.Real class A circuitry, clean reception without IMD.One coax connection.Broadband R/C coupling to the receiver, no transformer For best signal-to-noise ratio:install the Miniwhip onto a well grounded mast.connect "GND" of the Miniwhip PCB to that mast.place HI-Ui ferrite cores (Ui bwtween 5000 and 10.000) on the beginning and end of all cables to block cable noise currents. Specifications: Frequency range: 10 KHz - 30 MHz Power: 12 - 15 volts at 150 mA Second order output intercept point: Greater than + 70 dBm Third order output intercept point: Greater than + 30 dBm Maximum output power: in excess of - 15 dBm PCB Size: Length (mm): As the picture show Connector: BNC Feed line: 50 - 100 ohm coaxial cable up to 100 meter long T o note please: Each antenna performs as good as its installation permits it to. Any active antenna is not working good inside the house! It should be mounted OUTSIDE and as high as possible.
