The above results indicate to me that my HD8200U antenna is likely working just fine. The balun, pre-amp and cabin coax cabling are not causing problems. Antenna direction is fine since I was able to tweak against real channel 7 which is also located on Porter Mountain…… Other Thoughts Welcome!!

Thanks again,

Phoenix, Arizona shows K03FB on the air:

Either it isn't on the air or you have a high noise level on CH3.

I suggest you call the KAET station engineer at ASU.
