The COMPACtenna 28-450 uses a patented design which includes magnetic-field-enhancement. This allows the extremely short antenna to perform surprisingly well for its height. This revolutionary antenna was designed by Dr. Jack Nilsson N8NDL and offers superior performance on five popular amateur bands. Coverage includes CB, 10 Meters, 6 Meters, 2 Meters, 220 and 440 operation! Power capacity is 150 watts on 10, 6 and 2 meters and 100 watts on 220 and 440 MHz. The antenna is only 2 feet tall (with 4 inch diameter coil and resonator). Gain is +3 dBi nominal.
The new COMPACtenna 27-450 is essentially the same design, but additionally covers 11 meters CB.
The 28-450 and 27-450 antennas require a sturdy 3/8"-24 mount not included. This antenna may be used in as a mobile or base antenna with an appropriate mount and ground plane. In a mobile scenario, the vehicle provides the ground pane. In a base scenario, a ground plane must be supplied. In the example shown above, a simple 3/8x24 magnetic mount has been set on a 36 by 48 inch galvanized metal plate (available from Home Depot). The result is a compact, yet effective antenna for CB, VHF amateur, scanner monitoring and preparedness applications.
