Old cobra vs newer stryker

Full disclosure I know very little about cb radios. When I started driving full time in 1997 I bought a new cobra 148. In 2019 I bought a new to me truck( 2013 t660) and figured why not get a newer radio and bought a used stryker 497hpc from a friend. Installed new coax and antenna (single firestick 4') and ran the old cobra at first then switched to the stryker. The old cobra could hear for at least 10 miles with almost no background noise whatsoever. When I switched to the stryker it seemed as though 2 miles ish was the best I could hear and even then with a good amount of background noise. I am certain the stryker can be heard much farther as people could hear me much farther away than I could hear them. Just curious seeing as how everything else being equal is that a normal thing for each of these models of radio or is there more to the story that I can do to make the stryker perform better. If I could combine the transmit power of the stryker with the listening capabilities of the cobra life would be good.

 

I believe the stryker was worked on at the petro in Atlanta Ga. No clue exactly what year or what was done other than conversion. I appreciate the opinions. I have somewhat drawn the same conclusion. I hate that it is so old but will say it has been a great radio for many years. Figured it would be cool to try something new but so far has been a bit disappointing.

 

Mostly was curious if the stryker would require any different setup than what the cobra worked successfully on. Appreciate the thoughts.

 

Have not yet. Figured a top load was best for

I have not yet. It seems to me the low mirror mount on t660 kinda limits options. I may be wrong about that but have always thought it. Have considered moving antenna to top of headache rack to get it higher and try a different style.
