How to Install a UHF & VHF/DAB/FM Diplexer
Summary: A UHF & VHF/DAB/FM diplexer is used to combine the output from 2 aerials i.e. a VHF/DAB/FM and a UHF aerial into a single satellite cable that can then be distributed. There are various types of diplexers but they all have the same basic format of 2 cables in and 1 cable out.
Tools Needed
- Snips
- Screwdriver
Equipment Needed
- VHF/DAB/FM aerial (qty: 1)
- UHF aerial (qty: 1)
- Diplexer e.g. Fringe VHF/UHF/DAB/FM Diplexer (qty: 1)
- Satellite cable
Procedure
- Take an assembled UHF and an assembled VHF / FM radio aerial / DAB radio aerial
- Cut the satellite cable coming from each aerial so that it is long enough to allow the aerials to be mounted on a pole without the aerials touching each other and be fed into the bottom of the diplixer which should be mounted below the 2 aerials. Estimated length is .6m - 1.2m
- Pare down the end of each of the aerial cables and the output cable
- Squeeze on the clips on the outside of the diplexer and clip off the cover
- Insert the satellite cable from the VHF/FM/DAB aerial into the corresponding hole on the base of the diplexer
- Use the screwdriver to tighten both the core and earth wire into their respective screw and saddle & clamp locking mechanisms
- Repeat the procedure for both the UHF and output cables
- Leave the output cable long enough to reach the RG6 cables that are feeding into the various TV points in the house
