Query: Worked best out of circuit

Maybe mine was defective (I returned it, didn't want to waste time trying to get it checked out). My signal was pretty good (analog cable), but went thru a splitter, and was slightly degraded on some stations. With this booster, it was a lot more degraded. I swapped it with a simple male-to-male barrel connector for testing, and the picture was much, much worse with this booster.
