Product Description
Streamline Tetra Filter 380-430MHz
The BLA-RF-CAT-TETRA is a high-performance inline filter designed to protect TV, FM, and DAB signals from interference caused by TETRA emergency service radio transmissions. It features a deep rejection band between 380MHz and 430MHz, providing over 45dB of attenuation to block unwanted frequencies while allowing standard broadcast signals to pass with minimal loss. Built with professional-grade components, it ensures signal stability in areas with high radio traffic or near emergency service base stations.
Features
- Deep Rejection Band of 380–430MHz with typical attenuation of 45dB to block interference.
- Low Insertion Loss of just 0.5dB (typ) for low frequencies and 2.5dB (typ) for 470–530MHz.
- Wideband Compatibility ensures TV, FM, and DAB frequencies remain unaffected.
- Professional F-Connectors with a male-to-female configuration for simple inline setup.
- Compact & Robust design measuring 14mm x 61mm and weighing only 25g.
Applications
This filter is essential for installations located near police, fire, or ambulance stations where TETRA radio signals can cause "break-up" or total loss of digital TV pictures. It is designed to be installed inline between the antenna and the distribution amplifier or directly at the equipment input. It is particularly effective when used as part of the Blake UK Streamline RF-over-CAT system to ensure a clean, interference-free signal is distributed throughout the network.

Very courteous and helpful in dealing with my order error. A decent antenna delivered very quickly and I now have fm radio with a full strength signal.

I had a bit of a struggle with their online ordering, I managed to raise an order as "collection" rather than delivery by courier. However Blake's went out of their way to fix the problem. Otherwise their on-line service produces a good transaction trail.
