Sirius XM Sportster 5 Satellite Radio with proof of lifetime subscription SiriusXM

This is my personal Sirius Radio. I signed up for Sirius the day they launched the service 15+ years ago. I bought several lifetime subscriptions for each of my vehicles. Unfortunately the lifetime subscription will only transfer to 3 radios. This is radio #3 in this subscription so I can’t transfer it. I just bought a new car and it has SiriusXM built in so I no longer need this unit. In the photos, I have redacted part of the radio serial number but left enough for you to verify that this is legitimately a lifetime subscription. I had this permanently mounted and hardwired in the car. I installed a mounting bracket, direct connected to the radio, hardwired power, and a permanently installed antenna (see photo). This made it work at its best. I was unable to recover the antenna out of the car as I would have to remove half the dashboard to get it out without any damage. So I do not have an antenna for it. You can see in the photos that the radio works, properly updates as needed, and the cigarette lighter plug provides power. Q- Where can I get an antenna? Q- Can I use this with a boombox? Q- Can I use it at home? The item “Sirius XM Sportster 5 Satellite Radio with proof of lifetime subscription SiriusXM” is in sale since Friday, July 01, 2016.
