Connection for TV Antenna

71 International; I want to hook up a television, to the antenna, the wires in the box which I believe are for the TV, are not co axial wires. Am I missing something here? The wires appear to be bare copper wires, four of them. Is my unit missing something? any suggestions?

This makes me feel like my dad... "You young people aren't old enough to remember... "

Old-fashioned antennas used a 300-ohm dipole cable rather than the 75-ohm coaxial cable that's in common use today. I'm guessing if you have 4 wires instead of 2, there might be a line going to the antenna on the roof and another line going to some sort of connector on the side in case the campground had a "community" antenna.

Assuming the wires you found are for the TV antenna, you can get a matching transformer from Radioshack or other electronics store to convert the output from a 300 ohm "twin-lead" connector to a 75 ohm coax connector, to connect to the back of a modern TV. This will make more sense when you see the different adapters at the store. The matching transformer is only a dollar or two.

Also, if you are using an antenna to capture "over the air (OTA)" broadcast TV signals, and the digital TV signal is weak or non-existent, the antenna may be an older design that only received VHF frequencies. Most of the new digital TV stations are on UHF, which uses a different TV antenna. However, the Winegard crank up antenna on newer Airstreams receives both VHF and UHF signals. Not sure about older antennas; perhaps others can provide more information on those.

this thread might help.


if the four wire are red, green, black, yellow and very thin, they might be phone wires.

Your box is located on the street side behind the drapes in the living area...?

One set of wires should come from the rooftop antenna. The second set of wires should be a feed line to the bed area - where ours had a wall mounted tv shelf....

Welcome to AirForums by the way.

Is it 2 flat cables with wires on each edge? If so you can get an adaptor from flat wire 75 ohm to coax 300 ohm at Radio Shack or a place like that. Maybe even Wal Mart.
