The Maxview’s clear instructions help make it easy to set up and simple to use. It only has four LEDs, but these are bolstered by an adjuster dial for easy fine-tuning. It quickly found the strongest signal, indicated by only two lights. It comes with Velcro mounts, a 9V battery and adaptors. It’s the easiest to use, performs well thanks to its fine-tuning function and is priced competitively.
