The signal strengths of the LA stations are Very Weak.

And I see , Adjacent Channel Warnings Interference and Co-Channel Warnings Interference.

The Strong local transmitters interfering with the Weak LA transmitters.

As an example , KABC-TV REAL VHF channel 7 , and , KZTC-LP REAL VHF channel 7.

As a example , KVEA REAL UHF channel 39 , and , KNSD-DT REAL UHF channel 40.

As an example , KTLA REAL UHF channel 31 , and , KPBS REAL UHF channel 30.

And So Forth.

The LA Tv stations are , 80 Plus and 100 Plus miles away.

With 2 edge reception , terrain blockage , mountains.

This Is Not a Good reception situations.

This type and kind of reception situation is Experimental.

I recommend No amplifiers. As the amplifier will increase the strength of the adjacent and co-channels / local Tv stations channels.

This reception situation looks to be between , a rock and a hard place.
