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).

Response from Blake UK in every respect was very good and the product purchased is excellent. My only criticism is that the package that my omni FM/Dab aerial was sent in could have had more packing material as the carton was damaged in transit with a part of the product sticking out.

Good, well made coaxial TV antenna and F-Type satellite socket wall plate. It works well. The packaging could have done with some bubble wrap around the socket though for protection.

Super quick service. Please use less tape on the mast next time :-)

I already knew Blake from years ago. They are a quality vendor. The first BLA-LP56K was damaged by the courier in transit and they replaced it straightaway no quibbles the next day. This worked a treat in the loft with a masthead amp (have power in big loft). C/N : 30dB, sig: 100%, quality:100%: BER: 0.0. The aerial was connected into an IRS as the rooftop aerial had failed probably due to water ingress in the balun and I was quoted from £250 - £450 for a replacement outside antenna, probably because we have a very tall house/outside installation.Why bother when you know a log in the loft is going to work 11 miles from a 200kW station. As Blake say this is suitable for medium or strong signal areas but the addition of the masthead boosts the signal nicely for all round the house distribution.
