If you are using the “wire” antenna connection, the auto tuner will attempt to tune the wire for the frequency you have selected.
It sometimes takes a minute or so to tune. You may hear the mechanism reverse direction once or more. If the tuner cannot tune the wire the tuner will stop and the display will indicate an error.
If you hear a clicking noise and the unit errors out, the mechanism is probably stuck and requires service.
My experience using the wire antenna at different locations in the house resulted with about 300 feet of coverage at best. Using a longer wire usually won’t work as the tuner is designed to work with about 8 feet of wire.
Currently, I am using the ATU remote antenna mounted atop the TV antenna on the roof. My usable range is about 1/2 mile but can be heard farther depending on weather, time of day, season, etc.
Be sure to use a 3 pin AC outlet (no 3 pin to 2 pin adapters) as the ground pin is the RF ground for the system.
I would think if you could mount the transmitter in a weather proof box you could obtain the same result as using the ATU by attaching a whip antenna to the box and connecting it to the wire antenna terminal. Not very convenient as you’d have to run AC power and an audio line to it.
As for connecting coax to the transmitter “F” connector, without the ATU, this would require some experimentation to obtain the proper match and most likely would not satisfy the terms of the certification.
