Product Description

Attenuator VHF/UHF 20dB Variable/DC Blocked

A convenient variable attenuator which can be used with confidence wherever line-power is present. This compact unit is ideal for use on the inputs of distribution amplifiers and similar situations where signal level reduction and adjustment is required.

Features:

  • Covers the return path, VHF and UHF bands (5-862MHz).
  • DC-blocked at both ports - avoids burn-out when line-powered.
  • Low residual insertion loss.
  • Excellent flatness of frequency response across the full 20dB attenuation range.
  • Surface mountable and includes a removable plastic body that allows easy connector/adjuster access.
  • Tamper-resistant (access to the adjustment slot is recessed).

Very prompt reply re order unfortunately delivery by DPD failed to deliver to address even though there was a person in. DPD delivered to a local drop off point for collection, the so called local post office which not that local!!! Otherwise there would be 5 stars!!! Product great and fitted to cover entry point of Sky cables into building as SKy's product has failed , plastic cracked and fallen off.

I bought a LNB adapter for a Sky dish to allow me to use a single outlet LNB. Fitted perfectly.
