Enclosed is the photo of a car antenna's mounting. Note it is a single pin. Also enclosed is a picture of my Baofeng's antenna post. Note that the car antenna is a single post/pin. The Baofeng's antenna has a pin inside a mounting. Thus, to measure the Baofeng's antenna you simply connect it to the nanavna. How to do the car antenna???
The reason I ask is experience with my old Toyota 4Runner's radio and my new Ford Lightning's radio. The 4Runner radio would work 50 to 80 miles from a tower. The Lightning will start to fade 20 miles from the same towers. Is the fault with the antenna or the radio???
Thank you for any cogent answer. larry
