Operating Frequency

Times-7 antennas generally come in two

different operating frequencies, these are

FCC

and

ETSI

.

FCC: 902-928MHz

ETSI: 865-868MHz

It is important that the operating frequency

of the antenna matches the region settings

of the reader. The frequency of the antenna

can easily be found on the back label of the

antenna.

Some antennas, such as the A1001 and

A1030 are wideband antennas, meaning

that the same antenna will work at both

FCC and ETSI frequencies.
