Just bought one with the hope that the billing of overload protection is actually true.
Currently using it in a spot with VHF Hi and UHF signals up to a Noise Margin of around 62 db. Unfortunately I am getting overload on many signals even when the gain is adjusted down to near zero. And when it is set at zero I lose a lot of stations. Did a comparison with the RCA Pre amp and no pre amp and both of these methods work far better in a strong signal environment.
Will likely be returning it for a refund. Have one more test to do at a home I own which is also in a strong signal area but has some weak stations in a adjacent market that I have trouble getting. Want to see if it will work better with those.
I suspect this is going to be a great pre amp in an area that has signals in Yellow or Red only on a TV Fool report. But in an area with Green rated signals, it won't work right from what I am seeing and you will either lose stations or see a signal break up on others.
