I’m looking to maybe get a replacement for my Dad’s CBs. He’s had the same ones for a while now. He can get out great, and from Cincinnati can get to Canada and sometimes Florida (on skip). He always complains though that his receive is terrible and he can’t always hear people come back. Can you offer me advice on how I can help him improve receive strength? Thank you.

The base unit is a galaxy 2517, with a Maco (Macco?) V58 omni antenna

Mobile is a Uniden PC66XL (Apparently it was built before I was born!) and a Wilson 5,000 antenna on it.

Does the addition of a linear affect receive or just output?
