It's the H.A.A.R.P Array that Gov Jesse Ventura tried to warn us all about!!!
That not static - it's mind control medicine!!!
a) Seriously though - if two different radios alternately using the same antenna are both having the same static noise - you cannot blame/fault the radios.
b) Furthermore - antennas don't create static; they receive it. Static accumulation can occur around an antenna; but if one has their antenna mast grounded to the grounding rod properly with a good connection - then the antenna also shouldn't be an issue.
c) If the coax was to get soaked with water and ruined; you would see a bad match on your SWR meter. Check it. And check the cable for being cut, frayed, or just plain weather/time worn.
d) A faulty power supply can also be a noise monster. Use another power supply if you have one. Or power the radio from a borrowed car battery just long enough to see if it works OK that way. If the radio sounds clean powered with the battery; then the power supply filter capacitors are going bad and need to be replaced. Don't try to fix the power supply yourself unless you know what you are doing. Don't use a battery charger while using the battery; they make a LOT of noise/static and it will be heard in the radio!
Chances are - by the careful elimination of each part in the system by troubleshooting - you are probably going to find out that you are getting noise from a power pole that has bad insulators. Or - a nearby cable TV/Internet box that has poor grounding or a possible RF leak. A lot of people have these problems these days; one must hunt down the source by process of elimination. Once found, notify the power company or the cable company and make them aware of the problem and ask them to fix it ASAP (ASAP to the power company can take a while. ASAP to the cable people is usually pretty prompt. That's my experience - yours may vary). To be sure, ask a local friend that has a mobile radio to come over and see if his radio gets noisy when parked near your radio shack/room. There has to be something that is generating the radio frequency interference close to your location - the second radio should verify it. This will help confirm your diagnosis for the cause of the problem when you make your complaint.
Either that - or Jesse Ventura was right!!!
Put on your tin foil hats QUICK!!!
