[QUOTE="Don379, post: 11639622, member: 311957"]Setup Same for the past 4 years which is: Mirror mount wilson 2000 5" shaft and wilson gum drop mount. Mounted on mirror of peterbilt 379 at angle 8' RG8X astatic coax Cobra 29 ltd chrome edition (yes the chrome edition is slightly different than the classic" Astatiic mic Radio has been acting up past couple weeks so i swapped in a new coax, new antenna and new mount. Astatic mic crapped out on me today so installed a roadking 56 When i initally installed all my stuff years ago, i did so with my buddies good external swr meter and got my readings of 1.2 on channel 1 and 40. And to be honest, the cobra built in meter was pretty much dead on. Move ahead now, installed new components and tuned my new antenna last week with just the cobra swr. I have loud and clear 1.2 readings. I come in loud and clear for miles and transmit same way. I went ahead and bought a cheap 20 dollar astatic swr meter to verify, and the unit is telling me that my swr is in the red at 4. I figured maybe it was defective and forward at ref were reversed. but that wasnt the problem. I borrowed my buddies unit again. Low and behold readings of the same 4 swr. Whats going on here? The mic crapped out and also antenna light will blinking when transmitting. Grounds are great and cleaned the mirror grounds and have good ground plane. Also checked my ohms on the grounds. IS my cobra going out? Just doesnt make sense becuase its loud and clear but every so often i will get a bunch of static[/QUOTE]
