I purchased this in order to get a clear and consistent signal from a local PBS tower 28 miles away. All the other major channels were already coming in clear. Although this preamp is meant for outdoor, i connected it to my indoor flatwave antenna that i have mounted on the window. The set up was straightforward and easy. Not much of instructions, just a diagram for the respective hookups. You must supply your own stand alone coaxial cable to run it from the preamp to your TV. I would advise going to the Wineguard website to obtain more information.
After completing the hookups and plugging in the ac adapter, the PBS channel came in loud and clear. I was astonished. Surfed through the remaining channels to check if there were any distortions caused by the preamp. All was fine. The preamp is laying on the windowsill. I kept the TV on the PBS station , and after half hour there was some distortion, intermittently, but the station didn't black out. Probably due to high interference during that time of day in the Big Apple. Now it is evening, and the interference is gone.
This has been a 100% improvement in the PBS station quality. Very happy with purchase. Can't wait to watch Luther on (BBC series) , restarting in January. Happy new year!
Pros: Easy Installation, excellent signal
Cons: kind of pricey, plastic housing looks cheap and might crack.
