What are the transmit and receive frequencies for UHF loopback?

In a UHF loopback configuration, the transmit and receive frequencies typically depend on the specific system or application being used. Generally, for UHF frequencies, the bands range from 300 MHz to 3 GHz. However, in a loopback setup, the transmit frequency is often matched to the receive frequency to facilitate testing and diagnostics. For example, in a common UHF loopback scenario, both the transmit and receive frequencies could be set to the same frequency within the UHF band, such as 450 MHz.
