Something wrong with the external television antenna or you simply don't have one?
One of these can save the day, easy to instal and it may solve your problems
Simple flat panel design, like a Wi-Fi antenna - no more fiddling with the old "rabbit ears" to get the television signal "just right"
RCA Television Antenna
VHF-UHF
Non-obtrusive flat black panel
Measures 230mm x 210mm x 20mm thick
Weighs 400g (not too heavy on the wall)
Has holes in the rear for hanging on a hook or push fit to a wall
2 metre long coaxial cable with F connector at the end
*** NOTE ***
While these internal television antenna's can "save the day" if you don't already have a good external antenna, these are only as good as the signal strength you are receiving.
Don't expect miracles, if you are in a "dodgy" television reception area (in the basement, down a gully or simply a long, long way from the station transmitter) then this antenna will NOT help you out.
