Thanks you John Candle for all the feedback. You saved me from running off and buying an omnidirectional antenna.

The exact location of my receiver is 32.284721 -110.734161

I have now attempted a full 360 degree rotation of the receiver, rescanning the channels every 5 degrees. In doing so I have verified that pointing the antenna directly at the Repeaters (253 degrees True North) gives me the best results, using my current antenna.

I now get the following Real channels: 13, 16, 28, 40, 44

I knew I had no shot at picking up 25 (FOX) because they don't have a presence at the repeater location. The real mystery though is why I can't pickup 4 (NBC). That is very disappointing.

This is the info on the channel 4 transmitter:
K04QP-D 4 (4.1)
NBC
Max ERP: 0.300 kW
Eff. pwr: 0.300 kW
Rx: -49.7 dBm NM: 41.3 dB
Az: 253.1 degree (true)

Perhaps my antenna won't go that low in the VHF range? If this is the case is there something I can add to my antenna to pull in NBC?
