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).

Blake UK Ltd I was pleasantly surprised by this Sheffield Company. They're easy to order from,in my case online and email and text communication as I lip read, the item was ready to collect as per the order agreed. Far better service than Amazon for the said item still on back order with Amozon with a delivery date as far away as November 2024. I think it's probably come full circle, and shopping experience might be coming back, and with a company like Blake UK...I'd happily recommend them over and over. Well done ?

A REFRESHING CHANGE. Needed more info on an item. Fast response, friendly, informed, clear, offered alternative suggestion.... First experience with "Blake". Couldn't have asked for more. Thanks a lot Blake. I'm buying.
