- Inline LTE blocking filter up to Ch. 57
- F-Type connections
- Power pass
- For external use
Product Description
F Type Inline LTE Blocking Filter 35dB LTE A Block - 55dB LTE C Block (upto 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.
- F type 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 licences 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).

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.
Exactly what I needed and delivered when said great team
