The COMPACtenna 2m/220/440, a very small multi-band antenna that fits an otherwise unmet need by Hams for an attractive mobile antenna that allows vehicle passage in garages, etc. without having to remove or tilt their antenna. Due to the COMPACtenna patented design which includes magnetic-field-enhancement, this short antenna performs surprisingly well. And it includes 220 operation in addition to 2 meters and 440.
The antenna, designed by Dr. Jack Nilsson N8NDL, is only 7.5 inches tall yet covers the three most popular VHF/UHF bands! Coverage is an amazing: 144-148, 219-225 and 420-450 MHz. The small, rugged antenna provides high performance as a result of its unique electric/magnetic field diversity design. The patented design uses the the latest science to provide revolutionary performance in NLOS (Non-Line-Of-Sight) obstructed environments such as behind buildings, in garages, behind other vehicles and in valleys. Nominal gain +3 dBi. VSWR: <2:1. Power capacity: 85 watts on 2 meters and 50 watts on both 220 and 440 MHz. This antenna requires an NMO type vehicle mount and coax cable which are not included. Please see table below for typical mounting methods. One year limited mfg. warranty. Made in the U.S.A.
The COMPACtenna 2m/440 is identical, but does not include '220'.
These antennas may also be used as high performance compact base antennas at the top of a metal mast such as with the optional Larsen BSAKIT. Specific instructions are provided on the Manufacturer Data Sheet provided with the antenna. For best results with this mount, carefully bend the ground plane radials downward 70 degrees below the horizon.
