XM is given a stronger transmission level and also has a much more extensive repeater network to cover the trouble areas. Their antenas don't have to filter Sirius signal since their broadcast will overpower the Sirius signal.

I mounted my Sirius antenna outside with heavy duty double-sided tape in the bottom driver side corner of the the windshield. The windshield has black surround so it is hidden unless you really look.

My Sirius antenna is on the back deck, between the speaker on the driver's side and the third brake light housing. Reception is okay for the most part. My other car (a Honda) has a factory XM installation with a roof-mounted antenna and it gets far fewer dropouts. My wife just got a new GTI with a factory Sirius installation with an external antenna and I haven't noticed that her reception is any better than my Evo's internal antenna location. Both are susceptible to dropouts from overhanging trees, low lying areas, and highway overpasses.

The XM in my Honda just gives better reception with less dropouts than Sirius.

Of course, now that XM and Sirius have announced that they are going to merge, which technology is going to win and who will have to replace their head units, outboard tuners, and antennae?

XM has the better tech but it will be a while until anything actually happens.

50/50 chance FCC won't let the merge happen. But they are working on dual band
radios/tuners. Merge won't happen for at least 9 mos. if at all.

They both operate on diff. bands too. No interference.

Actually, their bandwidth is almost completely overlapping and shared with WiFi, bluetooth, Cordless phones, microwave ovens, and other 2.4GHz hardware. Sirius antennas have filtering to block XM signal since XM has greater output. That is why a Sirius antenna won't work for XM but an XM antenna will work with Sirius.

Are you sure about that. Everything I have heard has said that they operate on two different spectrums.

Posetive

If they merge what happens to the 10 million subscribers out there with receivers that won't work on the other service. The bandwidth is almost the same but the compression and transmission are completely different and not compatible. Sirius receivers can't tune XM but it can cause interference

merge not offical yet.....has to make it past the government and anti-trust laws. so as of right now they still operate independently of each other.
