Figure 6 Antenna Isolation Measurement - Equipment Configuration
NOTE: If the repeater uses a dual polarized, back-beam antenna, antenna isolation must be measure
from both ports of both antennas (four measurements). If the repeater uses only one dual
polarized antenna, only two isolation measurements are needed: one from the left port, and one
from the right port, of the subscriber antenna.
In all cases, measure antenna isolation with all cables, connectors, and lightning arrestors in
place. Record all measurements for future reference.
