Sole purpose is combine the feed from a VHF Aerial and UHF aerial into a single feed
ADVANTAGES of VHF UHF Diplexer
Solid and robust diplixer with excellent click down lid design
Effectively combines UHF and VHF especially when Aerials are mounted outdoors
In strong signal areas can be used in conjunction with a splitter at least 4 different TV points with little signal loss
Much less expensive than a either a Triax VHF UHF diplexer or powered distribution system which would also combine VHF and UHF aerials
DISADVANTAGES of VHF UHF Diplixer
Not quite as user friendly as Triax diplexer as it has Saddle and clamp rather than F-type locking mechanism
May not give good results if aerials are mounted indoors
Alternative options for very poor reception areas or if there is multiple connections is to:
Use a VHF/UHF Masthead Amplifier and a Power Unit
Use a 2 Input Powered Distribution System
Summary: A UHF/VHF diplexer is used to combine the output from 2 aerials i.e. a VHF 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
Equiment needed
VHF aerial (qty: 1)
UHF aerial (qty: 1)
Diplexer e.g. Fringe VHF/UHF (qty: 1)
Satellite cable
Procedure
Take an assembled UHF and an assembled VHF 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 feed into the bottom of the dixplixer which should be mounted below the 2 aerials. Estimated lenght is .6m - 1.2m
Pear down the end of each of the aerial cables and the ouput cable
Squeeze on the clips on the outside of the diplexer and clip off the cover
Insert the satellite cable from the VHF 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 and 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
