Swr problem my Wilson 5000

Quick question that i thought about.. what is a better mount, stainless steel or aluminium? or does it not make a differance?

 

I don't know that it matters. I always tried to stay away from the dis-similar metals thing. But, aluminum brackets are on literally thousands of chrome mirror arms. No matter which way you go, you should loosen the bracket up and clean the corrosion out every now and then, and check/clean your ground connections too.

 

I have a bc880 with a wilson 500 and ms500 amp. With or without the amp connected I see a swr of 1.00 on any channel. all test's pass is something wrong with this?
