they work great at 100 MHz (for the FM band) but yeah absolutely useless
at around 1 MHz for the AM band. silly store-person.


You disconnected it from the TV and used one side of the 300 ohm TV
antenna lead to a roof mounted TV antenna as a long wire antenna. They
were usually 50 feet or more and did work, but a longer wire was
definitely better. Silly you.

We tried inner core, shield, or both together.

No combination worked.


Does the coax go through a ground block? If it does, it is shunting
the RF to ground. I did it when 300 ohm twinlead was common.
