OTA reception Chandler TX

Hi,

I am going to install an antenna in a friend’s attic. Report attached. Can someone tell me which direction to point it?

I will be using some equipment we already have. Equipment suggestions are welcome in the event we do not get the results we’re hoping for...

Thanks,

Bill

Hello, Bill

How well an antenna will do in your friend's attic depends upon the attic construction; the signal loss is difficult to predict. If he has an aluminum foil thermal barrier, it will block the signals, and so will trees in the signal path.

As a double check on the accuracy of the TVFool report, because there have been many changes as a result of the FCC UHF Repack, here is a report by rabbit ears.info:



As far as antenna aiming is concerned, it will depend upon which channels he needs. I assume it will be:
KETK NBC, real channel 22, at 151 degrees true, 148 degrees magnetic
KLTV ABC, channel 7, 43 degrees
KFXK Fox, channel 31, 96 degrees
KYTX CBS/CW, channel 18, 140 degrees

He will need a UHF antenna with a wide beamwidth aimed at about 125 degrees for the UHF channels, and a VHF-High antenna aimed at 43 degrees for ABC.

For UHF, perhaps an Antennas Direct C2V

The C2V does have a VHF dipole, but it might not have enough gain if not aimed at channel 7

For VHF, perhaps a 30-2475

The two antennas can be combined with a UVSJ UHF/VHF combiner.

The TVFool Interactive map green signal lines can help with the antenna aim. You can move the marker by drag and drop to the antenna location:

Thanks for the quick reply. I actually have the c2v. I am going to try it by itself first. Hopefully it will work. If not, I’ll dig into your other suggestions.

Thanks,

Bill
