"High performance home antenna with compact, weather-resistant design connects to your SIRIUS home receiver so you can enjoy satellite radio through your home AV system".

This is the describtion for the Monster Indoor Outdoor antenna. Notice it says "High Performance". Is this really "high performance", is it any better than the same Sirius brand antenna? I currently have a Sirius magnetic car antenna just sitting in the livingroom window. I'm in an apartment, so there's no drilling holes to run a wire outside. Living in an apartment presents some reception challenges. My current antenna set up works....most of the time. Would this Monster antenna help, be better than what I'm using now? Thank you.
