EC Inline LTE Blocking Filter 35dB LTE A Block - 55dB LTE C Block (upto ch 57)
A convenient low-cost filter for overcoming interference to broadcast reception from LTE (4G) mobile networks.
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.
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 75 Ω 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 24 V and 250 mA max.
Usable for channel 58 with increased insertion loss.
Not suitable for areas where TV channels 59 and 60 are required.
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
