In my car I used to have a Pro-96 with the standard rubber ducky antenna and CHP Santa Rosa would come in loud and clear on their base freq. Now I’ve switched to my HomePatrol 1 in the car. Using the same rubber ducky antenna, CHP comes in almost never, and when it does it will come in and out (no static, just broken portions of the transmissions). I switched to a Diamond RH77CA antenna with no improvement. Does HP just not do good with low band? Is there a portable antenna that can do better with low band reception? Thank you
