Hi Clarbar. I also live in Milwaukee and receive stations OTA. As others have asked, can you narrow down your location a bit? I live in Bayside on the northeastern edge of Milwaukee County. I am able to receive everything with a cheap RCA yagi hanging in my garage rafters. I also get most everything in a guest bedroom with a cheap amplified flat antenna.
But your post brings up some interesting questions. Are you trying to receive TV reception from the wifi antenna? Antennas are designed to work at a certain frequency and the antenna length determines this. WIFI antennas are tuned to work at 2.4 and 5 GHz. TV antennas are tuned to three different bands as follows: (approximate frequencies)
VHF LOW (Chan 2-6): 54-85 MHz
VHF HIGH (7-13): 175-216 MHz
UHF (14-37): 470-610 MHz
An additional problem is that since the digital transition, the actual channel frequency may not match the displayed channel number. In Milwaukee it is as follows
Displayed channel Actual broadcast channel
4.1 (NBC) 32
6.1 (FOX) 33
10.1 (PBS) 8
12.1 (ABC) 34
58.1 (CBS) 46
24.1 (MyN) 25
18.1 (CW) 18
So, under the current setup, you need an antenna that receives VHF-HI and UHF. But as harshness pointed out, you probably want something for VHF-LO to futureproof for the upcoming repack.
BTW, here is my tvfool
