Installing the Antenna
Satellite radio delivers a static-free signal. That means either you get great sound or nothing—there’s no in between. This is where having a good antenna comes in. The car kit includes a small black square antenna that has about 20 feet of wire attached to it.
The antenna must have good access to the sky above to get the satellite’s signal. I’m mounting it where the dashboard meets the windshield. The antenna has a magnetic bottom to secure it, but there’s nothing metallic around so I use Velcro to keep the antenna in place.
Other mounting spots include the back of the rear-view mirror, the rear deck of the car, or on one of the bumpers or the roof near the sunroof opening (if you have one).
