Product Description

Overlap Blocking Filter Pass 48-60

A range of UHF band-pass filters from Proception, intended for blocking unwanted reception of transmissions from an adjacent region.

The introduction of high-power digital transmissions has led to problems with some receivers selecting multiplexes from out-of-area transmitters, leaving confused viewers watching the wrong regional services, or even listening to the wrong language!

Although this problem should be solved in the longer term by receiver developments, the use of band-pass filters can provide a quick, simple and cost effective solution, saving installers frequent call-backs.

Other Applications:

The entire range offers excellent cut-off below 470MHz and will help with problems from TETRA, telemetry and 70cm amateur band transmissions. Above channel 62 all versions will help solve GSM mobile phone interference problems, while the A and B models will additionally help suppress the forthcoming LTE (4G) signals.

Features:

  • Optimised pass-bands cover most UK requirements in just four versions.
  • Good out-of band rejection helps block TETRA and GSM, also LTE (4G), depending on model.
  • F type connectors for good screening factor, helping prevent leakage around the filter.
  • Good 75O match throughout the pass-band.
  • DC blocked, no damage if inadvertently line-powered (24VDC max).
  • Optional weatherproof outdoor housing available.
  • Equipotential bonding terminal.

Case for external installations


1. Specified stop-band rejection is typically maintained to above 2GHz (but is not guaranteed above 1.6GHz).
2. Insertion loss may increase slightly at the pass-band edges, but will not exceed 4dB.
3. Typical stop-band rejection is around 35 to 40dB except close to the band edges.

Frequently Asked Questions

An Overlap Blocking Filter (OBF) Pass 48-60 is a specific filtering mechanism used in signal processing, particularly in digital communications, to mitigate interference and enhance signal quality within the frequency range of 48 to 60 Hz.
OBF Pass 48-60 is specifically designed to target interference and noise within the narrow frequency band of 48 to 60 Hz. Unlike broader filters, which may cover wider frequency ranges, OBF Pass 48-60 focuses exclusively on this range to improve signal clarity.

I ordered a 1 in 2 out Hdmi switch but it was out of stock and rather than getting me to wait until it was in stock Blake UK sent a more expensive 1 in 4 out Hdmi switch at no extra charge. It was also delivered very quickly. I would there rate Blake UK ver highly - hence the 5 stars.
