FAQs

Q: Will 2 dB be enough to prevent receiver overload?
A: Check your transceiver output and receiver sensitivity. If received power exceeds the max, 2 dB may be sufficient for fine trimming; higher values may be needed for larger reductions.

Q: Does it support bi-directional operation?
A: Yes. Fixed attenuators are passive and symmetric for both directions.

Q: What polish is required on patch cords?
A: Use LC/UPC patch cords for optimal mating and return loss.
