Does the MR77B work on both 2m and 70cm?

Yes. It is a dual-band antenna with a quarter-wave radiator on 2m and a 5/8-wave radiator on 70cm, so one whip covers both bands.

How much power can it handle?

The maximum power load is 70 W. That covers most mobile transceivers, but not high-power amplifiers.

The base is a small 65 mm magnet. It is fine for normal driving, but check it before fast or windy trips and keep the cable clear.

Yes. The magnetic base and fixed cable let you lift it off one vehicle and set it on another, provided the roof or trunk is bare metal.

It saves space and one mount, but a dedicated single-band antenna or a larger dual-band model can give more gain and power headroom.
