Connecting coax to the 2 wires from my antenna

My 73 safari has antenna that goes up fine and I understand I can get local channels if I connect to it. I have a more recent flat screen tv.

There are 2 wires that come from the antenna and I need to connect them to a coax cable. Is there a specific kind of device to do this?

Will appreciate help.

You need one of these, a coax 75 ohm to 300 ohm adapter:

TV Antenna Adapter | eBay

You may be able to find one somewhere else too.

I was pleasantly surprised at how good an HD picture is just using rabbit ears on a late model TV. I hook it up to the antenna on my AS and it's like having cable. Of course, you have to be close enough to over the air (OTA) broadcast antenna to pick it up, but it's a very good picture.

I would think if you made the connection using the adapter Chris suggests, you'll be fine. I think they still carry those at Radio Shack, they're pretty common.

You are talking about this one where the 2wires connect and becomes a coax plug?

I wasn't sure exactly which part on the page you meant but this should work.

OP didn't specify which end of the cable he's trying to connect, the antenna end or the television end. For the antenna he needs a 75 to 300 ohm and he can connect a cable to the antenna. For the TV he needs a 300 to 75 ohm and he can connect the flat antenna wire to the new TV cable input. I'm not sure which wire he wants to have come down from the antenna.

That would work too. The coax end will connect directly to the coax input on your TV. If you want to change from the flat antennae wire to a coax cable, then you'll need a female to female coax adapter in addition to that adapter.

The one I was thinking of is here:

Indoor Antenna Matching Transformer Balun 75 300 Ohm TV F Cable Adapter | eBay

All depends on exactly where you want the adapter to connect.

Air broadcast TV signal

We have a 25ft Safari built in 2000. we have a newish Samsung flat screen HD tv. In campgrounds with cable, we get a nice picture. But I have not been able to get anything but snow when I raise the antenna and switch the Samsung TV input to "air."

I read in the owners manual that we have to have the switch turned on at the cable/TV wall plug just forward of the dinette. I tried that and still have nothing but snow. We have the original cable/phone box in the rear bumper storage area, and that's where we connect the cable at campsites.

How can we verify that the roof antenna is connected to that TV connection box by the dinette? Do we need to add something to the antenna because signals are now broadcast in digital form?

Help and ideas will be appreciated.

Is there a little button on the plate where the television cable goes to the wall? If you push it it should light up a little green led for the antenna amplifier. The other possibility is that something is disconnected in the back of the wall box. I have had more than one that was not connected properly.

If you are getting snow, your television is in analog mode. All off air is now digital and there is no snow on digital channels. If you are connected to cable and switch to off-air you must do two things.
1. You must press the button on the TV wall plate. This switches from the cable wiring to the antenna and powers up a preamp in the antenna.
2. You must point the antenna in the direction of your nearby TV transmitters and then use the menu function of your TV to scan for channels.

Off air channels are on different frequencies from cable and some cable systems may still use analog distribution. Your TV will not find stations unless you scan. When you go back to cable you have to reverse the above process. Push the button to turn off the led on the wall plate and rescan with your TV.

I hope I didn't tell you things you already knew.

You may have to program the channels on the TV. On my tv I have to go to menu options for antenna - on air - auto program - start.

Thanks a ton everybody. I did run the TV in auto program mode and now have 22 channels of HDTV. Makes me think about ditching Verizon in the house.
