Pros
I love testing antenna performance OTA. Been doing it since 2007. Most of all, making clients content and satisfied once their products met the carrier(s) specifications/requirements limit
Cons
No cons. Well, perhaps just one teeny weeny. Not all products are perfect and some will pass and some will failed the specifications per their carrier(s) Everything can't be nearly perfect. But eventually, it all worked out well. A little debug here and there. And VOILA!!! Success!!!!! Clients were content and their upper managements and so were we. Until the launched of their new next projects. Hand shook and off their way; safe trip home/office. Either domestic or overseas.
