Panel meter. As shown. Scales for mW and dBm. Has a spec of dirt or something on the inside of the clear face under the 2. We believe it might have been designed to be used in a portable instrument since it has a battery indicator range on the meter face. Meter face mounting hole needed is about 4-5/8" x 2-3/8". Movement seems to be free and dampens properly with shorting clip. Nice meter and movement.
