I used circa 45ft wire vertical with a few radials and k2 or k3. When connected directly or via a short run of TV line, the built-in tuner tunes down to 80 but 160m needs extra inductance. With BL1 balun any frequencies can be tuned but the balun gets hot. A better choice is to use an external tuner (without any balun) and connect the radio and the tuner by a balun. The balun made by wrapping 10 turns of RG174 on a  toroid is excellent and does not heat at all.

The performance with a  few radials is excellent at beachside locations (160m DX!) and poor inland especially if ground mounted and with lots of obstructions.
