I believe the head end unit of the antenna amplifier is defective.
It is on
the antenna.The twin lead from the antenna connection goes in one
end and
the coax goes on the other. The coax then goes to a plug in unit
in the
house which is connected to the TV.

The box at the antenna contains an amplifier.
The box at the TV end is its power supply.
The power supply usually is a small transformer putting
out about 13 Volts AC, which you can measure on the coax.
If you have voltage, the problem is probably up the tower.


Er, more usually d.c with +ve on the centre core.
