Satellite Radio - XM, Sirius?
Sirius is much better- without a doubt!!! They have 3 satellites, XM only has two stationary- the 3 Sirius sats are in orbit almost directly overhead- much better coverage. Shakespeare makes marine antennas for Sirius- nothing for XM- shows you who they believe in. Also, Sirius has 100% commercial free music and much better programming- plus you get free online streaming included with Sirius.
