If you will like to go after K39GY VHF channel 2 or is it UHF 39. That is the same as KHIZ-DT UHF 44 , KHIZ is received at your location. These channels may be transmitting Analog not Digital.

And KVTU-LP 3 ,
http://en.wikipedia.org/wiki/KMCA-LP , that is most likely transmitting as Analog channel 3 but might change to a UHF channel.
And KLAU-LP VHF channel 5 , that is most likely UHF Analog channel 45.

Then install a HD7084P ALL channel antenna.
All channel antennas receive All the channels that way All the channels are covered.
I say install a HD7084P All channel antenna and be done with it.
Aim the HD7084P antenna at about 105 degree magnetic compass.
