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).

Had to ring to see why I hadn't received my order, was told one item was out of stock, said they didn't know when they would receive the item but that same day it was sent to the courier, then still took another four days before I received my package,very poor packaging,hard to get into, one pole badly scratched and the other has a sticker on it that I cannot remove.
