Marcus could be right, but it's also possible that when making the switch
you damaged the very sensitive (and cost only a couple bucks) antenna balun.
It converts the 300 ohm antenna to 75 ohm feedline. Replace the balun,
available at any radio, tv appliance store, and see if that helps.

I just installed an omni-directional TV antenna using RG59U coax, but the
picture on some channels is fuzzy. During a test before permanent
installation, I used normal TV coax (black stuff) and the picture was
fine
on all the channels. Is RG59U the right ohm cable???

RG59 has the right 75 Ohm impedance but is not shielded enough for TV
antenna application. It is mainly used for video baseband.

RG59 is thus not approved for TV antenna/cable TV installations.
