More details on the Cobra HG A1000
Overview: The Cobra HG A1000 is a "cellular-style" CB antenna with a magnetic mount that easily attaches to the roof or trunk lid of your vehicle. It has an 18-1/2" mast and 2-3/4" diameter magnetic base, plus an attached 15'-9" braided coaxial cable (RG58) with a male UHF threaded connector. The Highgear-series antenna is designed for all CB and 10-meter radios, and is weather channel ready. It is covered by a 2-year manufacturer's warranty.
Construction: The HG-A1000 features a non-corrosive black chrome stainless steel whip that resembles a cellular antenna, with non-corrosive black chrome-plated brass components. The heavy duty magnetic base holds the antenna securely to your vehicle. A rubber base pad on the bottom of the magnet prevents scratches to your vehicle. The antenna is tunable should the SWR (Standing Wave Ratio) be out of acceptable range.
Tuning The Antenna: The metal body of your vehicle serves as the ground plane for the antenna. After mounting the antenna in your vehicle, you should test the SWR in an open area, using a SWR meter, or CB radio if it has a built-in SWR meter. The test should be run on channels 1 and 40. Readings of 2:1 are considered acceptable, while ratios of 1.5:1 or lower are desirable. If the SWR reading on channel 40 is higher than channel 1, you will need to trim the mast by 1/8"-1/4" using a bolt cutter or hacksaw, then retest. The whip is removable from the mast using the supplied 2mm set screw.
