Using an Indoor Antenna
Greetings Niners welcome to the Forum ! :welcome:
The advice from Don_M and ProjectSHO89 is good.
I have much the same situation here in Houston, that being a strong Antenna Farm just south of me, and am using some Rabbit Ears on a single TV portable system.
Don's term "barrel connector", is a "Union" which connects two Coaxial Cables together, allowing the placement of the Antenna, to a better location for reception. Just so you'll know what we're talking about, here's a picture of the...
Winegard FS8100
this is a bag of 6, and you should be able to pick just one up locally.
Here's an example of a Indoor VHF/UHF Antenna in the...
Channel Master CM 4020
Placement in an optimum location is necessary, but, Don's advice about the length of the extension Cable is wise. No longer than necessary, to achieve the placement.
Here's a typical Chart for the stations transmitting in Dallas Area...
Dallas TX. 75201 Typical Reception Chart
As you can see, you have an abundance of Stations to view, but, you do want to make sure in the placement/adjustment of the Antenna, that you have included all the Major Broadcasters if possible. (shouldn't be any problem in doing that)
The list of Channels shows the strongest at the top, and as you move down the Chart, they get weaker. So, let's select the last of the Majors, that being the WFAA, ABC, Ch 8.1.
After a Scan with your TV or Converter Box, either select this Channel by the up/down toggle button, or, manually enter it into the Tuner/Converter. This is the Channel, which you use to find the best placement/adjustment for your Antenna.
Understand, I'm not saying that you will receive ALL the channels listed on the Chart, probably far from that, but with this simple procedure, and once you have good placement for reception of Ch 8.1. the rest of the Major Broadcast Channels, should be able to be received satisfactorily.
Be sue to run through the other Major Broadcast Channels, and see if they are coming in ok. There's a lot of discussion we could get into here concerning the VHF Ch 8.1, and the others being UHF. So, if you have a problem with any, jut come on back and we'll talk about it here.
Have a good Day !
