Yes - that is correct 6m! The 2m/70cm rubber-duck antenna has a small top section that screws off and can be replaced with a 6m extension top.
Boxed and in excellent condition but .. the battery charger is currently missing (I am hoping a return visit to the SK's estate may unearth it). A new BC-08 charger is £15 but it looks like it is just 12v.
Currently £240 at UK supppliers. Even if you lashed out £15 for a new charger £100 has to be a bargain!
