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).

Good intial service, products arrived safely. Downside, found the products about 50% cheaper at another retailer who are reliable and trusted, so not lower quality and the aerial which was recommended for my area is not suitable and the quality of reception is worse then the original aerial.
