For price, see our offline price list section 8.03.

TETRA is a new digital mobile communications network for the emergency services. As the service is rolled out across the country it is expected that there will be an increasing number of interference problems created by this new technology on existing TV systems, large and small.
Many TV systems are relatively open to out of band interference especially where wideband equipment is used throughout. Those that are well filtered either through choice of amplifier or by the inclusion of a front end filter such as a cluster leveller should not suffer from interference.
teldis TETRA filters are designed to provide substantial stopband attention of the signals causing interference. The units are small fully screened and use F type female connectors.
Fixed frequency band stop filters have been produced for specific cellular telephone and TETRA bands. For In-Band interference a single channel stop filter BSFC/x - can be customer specified for any PAL I channel.
