NuVo NV-T2SIR Dual Radio Tuner, AM/FM & Sirius Satellite-Ready

You have to use included antenna. I can only pick up two stations with antenna on inside of house. Put back in box and use the reciever I already had. Complete waste of my money.

This tuner works great and it will work with external antennas , you just have to turn on the voltage in the setup menu, as the antenna that comes with it is an amplified antenna, but if you turn off the voltage you can use any antenna that you want. It will work with any system using the remote that comes with it or it works great with a Nuvo audio system to control it. You can use one or two external sirius tuners to interface with it.
