I am not sure actually this will improve quality of signal or power level, but one thing is for sure

Great service and good quality

excellent quality

VERY GOOD QUALITY ON TIME DELIVERY-

I use it to clean contacts and prevent corrosion mostly on a variety of electronic connections, as well as on RF connectors like PL259/SO239

i took the front cover off and coated the electrical pins then put it back in the truck and it hasn,t stalled since
