No, you won't have to subscribe to the SF2 subscription.

If you don't mind me asking, what is your dealership's fee structure? From what I've seen some charge a large initial fee and a small annual fee. Others have a smaller initial fee, a large annual fee for 1 unit, and a small annual fee that covers any units after the first one.

We put up our tower to get away from annual subscriptions. Salesman told us the other day that RTN is trying to find sites to place towers in our area and one of their projected sites was just about where ours is located.
