Holland Electronics FAM-20 20dB Inline Attenuator

SKU CH-EAJA-RY6VY

A 20 dB inline attenuator reduces overly strong TV antenna, cable or satellite signals across 5 MHz to 3 GHz with 5 % accuracy

  • FeaturesUniversal
  • Reduces excessive signal strength by 20dB for clearer reception
  • Maintains 5 % accuracy across 5 MHz to 3 GHz bandwidth
  • Brass C3602 body with nickel plating resists corrosion in RF systems
  • Return loss of 25 / 22 / 18 dB ensures minimal signal reflection
  • Stack multiple attenuators to achieve the exact loss required

Signal reduction for strong inputs

The Holland Electronics FAM-20 is a 20dB inline attenuator designed for coaxial cable feeds in CATV, off-air, SMATV and similar RF distribution systems. It lowers signal levels across a 5MHz to 3GHz range when incoming strength is too high for the connected equipment.

Simple coaxial insertion

Installation consists of placing the unit in-line on an existing coaxial run; no tools or power are required. Brass C3602 construction with 4µm nickel plating and an 8mm steel centre pin maintains a 5% accuracy specification and return loss of 25, 22 and 18dB at the stated reference points. Multiple units can be combined to reach a precise total loss if a single value is insufficient.

Suits installers taming hot signals

This attenuator suits technicians and home users who need to knock down over-strong UHF, VHF, FM or digital sources such as antenna, cable, broadband or satellite feeds without DC voltage present. It is not intended for applications requiring DC pass-through, variable attenuation or frequency ranges beyond 3GHz.

Questions about this item

How can I confirm the FAM-20 is reducing signal by the rated 20dB after I install it?

Use a signal-level meter on the coaxial line before and after the attenuator; a drop of approximately 20dB across the 5MHz-3GHz range shows it is working as specified.

What comes in the box with the FAM-20 and do I need any extra parts to install it?

The package contains the brass-bodied FAM-20 attenuator with nickel-plated F-type connectors; no extra components are required if your cables already have matching F-type ends.

Which attenuator value should I choose if I need a different amount of signal reduction?

The FAM-20 provides a fixed 20dB loss; for other reduction levels select a different model from the same series, or combine multiple units to reach the exact dB figure you need.
