I've used the Wilson 5000 magnet mount for years. If tuned to as close to a SWR of 1 as you can get, it gives very good reception. I mount it on the rear passenger side so the antenna pattern is primarily toward the driver side front and thus toward oncoming traffic. Bring the cable in at the bottom of the lift back, up under the cargo and floor mats to the front. Use it with a Cobra 25 with the built in SWR meter.
