Antenna Placement

[wjennings]

I'm on the East Side in a three story brick apartment building. The only windows I have face east.

Right now with my setup I get most of the channels and they're in the 50-70% range.

Amy I better off sticking the antennas in a window? Or leaving them where they are now?

Setup:
Samsung SIR-T151
Antenna 1, rabbit ears and UHF loop
Antenna 2, Zenith Silver Sensor
Both antennas into a combiner then into a RS 10db preamp.

TIA
