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.

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.

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.
