Terrestrial UHF Preamplifier With 70cm Notch Filter Orion 470-865MHz

Terrestrial UHF Preamplifier With 70cm Notch Filter Orion. This preamplifier features a frequency-compensated characteristic and is highly resistant to interference from HF, as well as 6m, 4m, 2m, and 70cm amateur radio stations. It includes an integrated 432.1 MHz –20 dB notch filter to effectively reject 70cm signals. Furthermore, 2m signals will be attenuated by more than 35 dB.

This low-noise TV DVB-T preamplifier operates within the 470-865 MHz range and is ideal for users experiencing RFI issues with their own or their neighbors’ TV signals.

In addition to this UHF preamplifier to combat interference on TV receivers, it is also necessary to consider VHF RFI Filter For TV Signal Reception or UHF RFI Filter For TV Signal Reception.

Place the preamplifier for weaker TV signals immediately after the TV antenna, using about 1 meter of RG6 coaxial cable. Do not use RG59.

The preamplifier itself will not work without a 12V 250mA supply. For the EU plug, you need to buy a power supply similar to this one. Version with “F” connectors or for different mains voltages, “12V power supply inserter” that we offer separately.
