Satellite radio antenna question
I recently installed an aftermarket stereo head unit that is satellite radio capable. While I currently do not have a subscription, I am thinking of getting one. My question is, will I need a new antenna or will my OE antenna be able to receive the sat signal?Clint (TX) 2001 Silverado LS 4.8L auto 2wd ECSB [GARAGE]

You will need a different antenna. Likely, you'll also need a separate module. Typically, 'capable' or 'ready' advertised head units have the ability to switch to an XM/Sirius source, but require an external module to enable that source. Check the manual for your new stereo.

Which radio did you get? I ask because I just purchased a new head unit and was told by the installer that I didn't need a new module as @dobey stated. I was told I may need an adapter to be able to hook it up. I believe that @SurrealOne also used an adapter for his HU. Not all HU may be this easy though.

I can't speak for XM radios, as I have SIRIUS. To connect my SIRIUS SCC1 to the OEM XM antenna on my 2004 GMC Sierra, I used a GM XM to SIRIUS adapter sold by TSS-Radio.com. Here's a link to the part: http://www.tss-radio.com/products/gm...a-adapter-plug

This is the exact unit I have:
Looks like I'll need an adapter. It's wierd though because the head unit has a sat signal indicator (bars, just like on a cell phone) but how does the know strong the signal is without an antenna?

In keeping things simple for here - The only diff between conventional radio and Satellite is the location of the transmitter. There's a lot more to it of course but that's it in a nutshell.
A Satellite antenna is designed to receive signals much less amplified than a conventional radio wave antenna and decrypt the encrypted Sirrius/XM signals. Your adapter will provide this function.
Looks like a nice unit too. I like the NOAA setup it has.

First unit I've seen with weather / emergency capability. My cousin is a retired Fire Chief so I'll tell him about this as he would like this living in florida.
