Delta Electronics AWA-1 Active Whip Antenna (Delta P/N 940-0023-001) Normally used with the Delta SM-1 AM Splatter Monitor.  The antenna has a whip that excends 43 inches above the base that has a magnet for easy temporary mounting on the roof of a vehicle.  The unit needs about 9 VDC to run its internal amplifier for the AM broadcast band.  This one has been modified with an additional BNC jack so it can output VHF frequencies, such as FM broadcast band.  That part is not amplied, it makes this item a convenient antenna so a spectrum analyzer could be used to monitor stations across the FM band or other VHF frequencies.    Used, but in excellent condition with schematic documentation.  $200.00.  Photo
