Easy-Tune is a combined signal finder & amplifier booster.
Plug your antenna into the Easy-Tune & use it to show which direction the strongest signal is coming from. Then using the handy LED indicators, the amplifier gain can be adjusted to fine tune your TV. The Easy-Tune can be permanently fixed inside your RV (perhaps inside a storage compartment). It is designed to show the presence & signal of digital or analogue TV signals & is also able to boost the received signal & distribute it to 2 outlets.
Note: you should never connect 240V AC (mains voltage) directly to the Easy-Tune.
