RF Repeater Oscillation
To prevent feedback, the donor and server antennas must be separated by an appropriate distance to provide
sufficient isolation. Isolation can be attained by separating antennas at a sufficient distance so that the output
of one antenna does not reach the input of the other. This distance is dependent on the gain of the repeater.
Recommended isolation value is 15dB greater than the user-set gain of the repeater. For example, if the user-
set gain of the repeater is 50dB, then isolation of 65dB or greater is required. In the same manner, to utilize the
maximum gain of 95dB of the PSR-VU-9537-UA, isolation of at least 110dB is required.
