Upgrade my MD 102 Tuner?

I can't use an outdoor antenna. A powered antenna doesn't work too well, either. So, it's just a standard, 75 ohm indoor antenna. The unit does not have the XM radio feature ... quite frankly, I wish there were some kind of module I could hook up to the MD 102 to play internet radio through it. Unfortunately, I have not yet found such a thing.

The tuner only has inputs for a 75Ohm antenna, there are no 300 Ohm antenna terminals. I'm using a standard 75Ohm dipole "T" antenna.  If you have any specific suggestion for antennae that will work well with this unit, I'm all ears.  Thanks.
