5-694MHZ 4G INLINE FILTER

The 700 MHz frequencies used by some 4G services are next to the frequencies used for FTA TV; there is a small chance this may cause disruption to FTA services. If you areexperiencing interference since your area retuned, this filter may assist in filtering out these signals.

Filters LTE/4G signals for interference free VHF / UHF
Installs inline
PAL Socket to PAL Plug
Pass-band Insertion Loss: 5~694MHz < 3dB
Stop-band Insertion Rejection: 720~1000MHz > 40dB

3-IN 8-OUT MULTISWITCH

Doss SMS38F multiswitch can be used with a dual LNB to distribute satellite TV signals to multiple receivers from asingle dish and LNB. It features 3 input which means it allows you to combine a dual LNB plus an input from a terrestrial antenna.

This product saves the hassle of installing several satellite antennas for your multiple television subscribers needs.

It distributes your satellite system up to 8 output receivers.

Features

3 In ports (Dual LNB and Terrestrial antenna)
8 Out ports

Note:
Doss splitters will also function as combiners.

When combining modulated signals, leave at least a 2 channel separation i.e. Channel 21 for the first channel and Channel 24 for the next etc.
It is also recommended that if you also have an antenna connected to the system, you use a Digiair Pro when selecting the appropriate channels. The spectrum analyser function will display where there are the lowest levels of interference i.e. where the modulated should be placed in the radio spectrum.
