Review on Winegard LNA-100 Boost TV Antenna Amplifier - HDTV Signal Booster with HD Digital VHF UHF Amplification - Indoor Ultra Low Noise Amp (USB Power Supply) by Rushabh Bear

TL:DR -- With a weak antenna, the most drastic improvement was to connect the LNA-100 between the antenna and the 50-foot coax cable to the living room wall panel place. When the LNA-100 was placed between the wall plate and the TV, there was only a slight improvement over baseline. YMMVLong Version: My setup is a very small portable antenna hidden in the attic, 50ft of cable run, TV. This is the guy that looks like a metal hot dog on a round magnetic base. Before installing an amplifier somewhere in the chain, I could pull 42 local channels, but everything on VHF was marginal. It was a mix of DC and Baltimore channels. I had no usable CBS at all. With the antenna connected directly to the TV, I generally had the same channels, but they were more susceptible to interference. LNA-100 on TV: I upgraded to 53 channels. I took the second NBC. CBS 13 on RF 11 ran on an "out of service" schedule, but popped up occasionally. LNA-100 on loft antenna / up to 50ft coax: I upgraded to 67 channels. Baltimore CBS WJZ on RF 11 became stable. Although closer to Baltimore, I picked up ABC WJLA from Washington on RF channel 7. I had at least one usable local channel from each network and 4 PBS stations. YMMV: My antenna is tiny and not designed to transmit large cables. With a better antenna (which most antennas would be) I would imagine it would work as well or better on a TV. Try both. One will likely work better than the other for you. In both cases I saw an improvement.
