In summer I have the top off for a few days here and there, just make sure those days there is nothing anywhere in the car, all kept locked up in the console. Could take the uhf I spose but that gives me an excuse to get a new 80 ch
If there is nothing easily avaliable and they do something to the car, I figure they would be the same type of inbreds who would pinch outside stuff anyway (lights, aerial etc)
Have the alarm on doors and hood/bonnet so thats good enough. Hear anything and me and the big boy mastiff will be out in a second
