LTE Inline Blocking Filter, 35-55dB to Ch57, IP55 Waterproof
Product Code: PROLTE1-57C
- Inline LTE blocking filter up to Ch. 57
- IEC coax connections
- Power pass
- For internal use
Product Description
IEC Inline LTE Blocking Filter 35dB LTE A Block - 55dB LTE C Block (up to ch 57)
Features:
- A convenient low-cost filter for overcoming interference to broadcast reception from LTE (4G) mobile networks.
- Passes all terrestrial broadcast transmissions up to and including TV channel 57.
- High attenuation in LTE bands, will cure the majority of interference problems, from both base stationsand mobile user equipment.
- Low insertion loss and good 75O match throughout the pass-band.
- IEC connectors with good screening factor, helping prevent leakage around the filter.
- Male and female connectors allow insertion into existing systems with no need for further cables or back-to-back adapters.
- Power-pass: this is a pure low-pass filter and passes AC and DC line-power.
- Waterproof housing, suitable for outdoor applications when used with suitable mating F connectors. (Rated to IP55)
- Power pass rating 24V and 250mA max.
- Care must be taken to avoid interference pick-up after the filter. Attention must be paid to the quality of components such as flyleads and outlet plates, etc.
- In severe cases two filters may be cascaded by screwing them directly together. This will of course increase the insertion loss.

- For the purpose of this specification the LTE downlink band is split into three 10MHz wide blocks designated A, B and C. Block A is further divided into two 5MHz sub-blocks. The LTE e-EUTRAN air-interface specification allows for flexible transmissions of 5, 10 or 20MHz bandwidth. Actual transmitted signal parameters will depend on the licenses granted to particular network operators.
- Usable for channel 58 with increased insertion loss. In TV channel 58 the pass-band insertion loss is increased to typically 7dB.
- Not suitable for areas where TV channels 59 and 60 are required.
- The introduction of new mobile telephony and broadband data services in former TV channels 61 to 69 (part of the digital dividend) is likely to cause interference to many existing terrestrial TV reception and distribution systems. This easily-installed low-pass filter can be used to overcome interference problems in many such systems.
- For two cascaded filters the pass-band insertion loss at 766MHz will be typically 7dB and the stop-band attenuation typically in excess of 76dB. (Figures given as typical values are not guaranteed).

Does the job - excellent.

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.

Excellent service, both before and after sales.

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 :-)

As usual, efficient service, great value products and easy to deal with.

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.
