The port features two operational LED indicators:
The Rx IF input port connector is a 50Ω Type 'N' female. The return
loss on these ports is typically better than 17 dB, and if the user
wishes to connect to a 75Ω system, an inexpensive 'N' to 'F' type
adapter can be used and is available as an optional accessory. While
there will be a reduction in return loss when doing this, the effect in
most systems will be imperceptible.
