![]() If you have an FM antenna, this is usually directed directly to the distribution amplifier and connected to the VHF input. Depending on how the wiring is already set up in your home, the cable would run from your aerial to your satellite receiver (if you have one), then the outputs from this satellite receiver would run to your main TV and distribution amplifier (UHF input). ![]() Cables to all your TVs would then be run from the output of the distribution amplifier. Usually this distribution amplifier would be in your loft. It can be used with digital (Freeview) or analog signals. Good quality coaxial cable loses about 0.18 db/meter, therefore a cable run of 40 meters would lose about 7.2 dB, so that the amplifier gain should be around the same or something more than this. The 2 inputs (UHF & VHF) are combined and distributed across the outputs (8db reinforcement per output). This ultra-broadband distribution amplifier can be used with one or more antennas, and is designed to improve picture and sound quality by amplifying weak UHF and VHF signals (FM and TV) and distribute these signals to multiple locations around your home.

Some FM traps slightly reduce RF channel 6 reception (VHF).ĤG/5G Filter - Also called cell filters, these preamps have the option to filter out cellular 4G and 5G mobile communication in the UHF band. The filter is needed when an FM signal is strong enough (a close FM transmitter) to overpower the preamp, preventing TV reception or reducing performance. Some cover VHF-Hi and UHF, some only UHF.įM Trap - Some preamps have the option to switch in an FM Trap to filter out the commercial FM radio band which is between RF channels 6 and 7 (VHF band). Most preamps cover the VHF and UHF frequency bands. Some preamps have an adjustable gain, others are fixed gain. Noise figures vary from 2 to 4 dB or more. Published noise figures are often based only on the amplifier, not the preamp housing input and output connections and internal cabling loss. The less noise the lower the noise figure, and the greater the signal improvement. ![]() Noise figure is a measure of the noise an amplifier introduces to a signal. Additionally, the closer the preamp is to the antenna, the better the signal improvement. Signal improvement depends on the preamp Noise Figure (NF), and gain. ![]() Preamps increase signal power but not noise ClearStream JUICE UHF VHF Antenna Amplifier
