My antenna wires go through a plastic cable pass-through tube in the wall to the outside. The white (hot) wire then goes vertical up the side of the house made of painted cinder block. Once outside the black (ground) wire is clamped to an 8 foot commercial grade ground stake.
What exactly are you using for an antenna? If you are just using a length of wire without a loading coil to compensate for its reactance, then it will radiate very little.
It may be that signal is so weak that it cannot overcome the AM noise present in many homes and neighborhoods these days from light dimmers and other sources. In which case the fix is to improve the impedance match between the transmit antenna and the transmitter.
