Review on 📡 10 Foot Universal Antenna Extension SBRGT-10 for XM Radio by Eric Cooper

I used these to run a factory XM antenna in my 2005.5 Audi S4. I think it was a green fork to anyone trying to do this. I didn't need an adapter and had about an extra foot when installing my XM Onyx ez Tuner. I can't report any loss of reception with this extension and it works much better than the antenna that came with the Dash. I know you shouldn't put the antenna on the dashboard, but I knew about this cable. approached and did not want to install and then remove another.
