F-Type Inline LTE Blocking Filter 35dBLTE A Block - 55dBLTE 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 59.
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.
Power pass rating 24V and 250mA max.
Usable for weak signal channel 60 areas with increased insertion loss.
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.

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.
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.
In severe cases two filters may be cascaded by screwing them directly together. This will of course increase the insertion loss.
