Product FAQ

1 What applications need a 20dB attenuator?

Large buildings, DAS installations, and areas very close to a cell tower benefit most from this level of attenuation.

2 Is 20dB too much for home use?

Usually, yes. It’s typically reserved for industrial or high-signal setups.

3 Can I use this to troubleshoot an overloaded amplifier?

Yes, it’s great for reducing signal temporarily for testing and tuning.

4 Is installation tool-free?

Yes, simply screw onto existing N-Type cable fittings—no tools required.

5 Will this reduce my indoor coverage?

It reduces donor input signal, which may slightly reduce overall coverage, but improves stability and reliability.
