I've been in "acquiring signal" hell since I got my receiver Christmas day. Since then, I've been eyeing the Terk Sir6 outdoor antenna. Looks like a nice unit, and most of the customer reviews for it on Amazon are quite glowing. However, it's on backorder everywhere I look - even the Sirius store. I tried ordering it from Amazon, and they gave me an estimated delivery date of February 13(!). What gives?
