my uhf/vhf (combo) antenna is only 5 years old. the cable plugs into the back of my tv. yet it does not fit into the coverter box "antenna input" hole. does anyone know why?

i have been reading that uhf/vhf antennas work with converter boxes. what do you think the issue is?

The standard round (75 ohm; not flat 300 ohm) antenna cable has a plug with a thin prong in the middle about as thick as a paper clip wire. If it doesn't push into the converter jack (stud) easily, it is OK to force it in.

Do not force in a plug prong that is thick like a pencil lead.

The shell of the plug may either press fit or screw on.

Flat antenna cables end in a pair of lugs or loose wires. You need to buy an adapter (300 to 75 ohm transformer) that typically looks like the end of your thumb and has two screws for the antenna wires and a shell with center prong that fits on the stud on your converter box.

What does the wire from the antenna look like?
Is it round, or is it flat?

If the cable is round, the connector should fit into the converter box.
If it's flat, then you need an adapter, which you can buy at Radio Shack.

If it is the flat type, I would strongly recommend upgrading to coaxial cable.
It is much, much less lossy than 300 ohm flat (twin-lead), and much less prone to spikes caused by lightning and other electrical disturbances.
You can keep the same antenna; Just need the adapter up on the antenna instead of at the converter box.

Can you post a photo?
