FREQUENCY BLOCKS AND RANGES

The table below lists the factory designated frequency ranges

available for the UCR200D receiver. For convenience, the table

includes information about the UM200B belt-pack transmitter

antennas as well.

Each UCR200D receiver is built to cover a pre-selected range of

frequencies (a “block”) as shown below. The receiver will tune to

any of 256 different frequencies within this factory assigned block.

The UCR200D UHF Receiver antennas (model A8U) are color

coded to indicate the frequency block that they operate within.

FREQUENCY

BLOCK RANGE

The length of the antenna varies with the frequency block. The

actual length of the antenna is not as critical as it might appear in

the table below. The usable bandwidth of the A8U antennas are

+/- 50 MHz from the center frequency, so it is acceptable to use an

antenna from an adjacent block above or below the operating

frequency.

The color of the antenna sleeve is in keeping with standard resistor

value color codes for the second digit of the block number. Block

23 is not used since it covers a 608 to 614 MHz band that is not

allocated for use with wireless microphones.
