 The C-4 is designed for reception of UHF channels 14-69.  You have VHF channels 8 KAET, 10 KSAZ, 12 KPNX, and 13 KOLD in Phoenix and Tuscon.  In your case the VHF signals are too weak to work properly unless you have a real VHF antenna.
Consider the HD7696P that's rated for channels 7-69 and use an AP-8700 preamp.
Because of the pair of double loops the C-4 looks to me like it ought to have an 88 in it's model number.
