Missing major OTA signal
Hello all, :confused:I recently cut loose from Directv and put up an antenna, but I can't seem to pull in the OTA signal from what should be the strongest of all channels in my area. I can get FOX, NBC and CBS but no ABC.
Antenna is rated for up to 165 miles. Antenna Frequency Range: VHF: 174-230MHz / UHF: 470-862MHz | Amplifier Frequency Range: VHF: 47-230MHz / UHF: 470-862MHz.With a Channel Master CM3414 4-Port Distribution Amplifier
Any ideas what I can check?

What is the antenna manufacturer and model number?

If unknown, can you post a picture?

Your ABC channel is at 240 degrees. What direction is your antenna pointing in?

Welcome, golfknut

Here is your tvfool report as an active link

The only difference I see is that KSWO ABC is a VHF channel.

Do you have trees in the signal path in that direction?

The only other thing I see is that you have a very strong FM transmitter only 0.5 mi away that is probably causing interference to ABC. You need an FM filter/trap.

We need more information.

And the antenna is pointing at 240 degrees and only a few trees may be in sight path, but sparse at best.
I'll try the FM filter/trap as Rabbit73 has suggested. I guess I don't understand all I need to about antenna.

Thanks, for the replies.

That antenna should be sufficient for your situation. Are you mounted
on the roof, in the attic or elsewhere??? How long is your cable run?
Anything over 50 feet and you really start to lose signal strength.
How close are the trees in the direction you need???

Mounted on the roof approximately 30' off the ground on flat terrain. Cable run is 40 foot to distribution amplifier and then to my 1st TV another 20 foot. Great signal for the 22 channels I receive except ABC. Trying to get ready for football season.

First thing to do is get the 2nd amplifier out of the system. You already have more than enough (borderline excessive) amplification from the built-in feature of that antenna.
