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.
