100m Coaxial Cable
The latest specification digital coaxial cable has an aluminium or copper metal foil screen to reduce signal loss as well as copper braid, forming a double screen. Double screening coax cable helps to prevent interference pickup and is essential to get the best digital TV reception, free from pixiliation, picture freezing and signal drop-out.
WF100 or PF100 coaxial cable (which is essentially similar) has a solid foam insulator which prevents water damage into the cable - a problem with the semi air spaced coaxial cables of yester year.
Two types of coax cable are in common use. RG6 is a cheap coaxial cable with a metal foil screen which is the minimum recommended cable for Sky TV installation work. It is slightly thinner than WF100/PF100 cable and has slightly higher signal loss. In general it is best to choose WF100 over RG6 cable for cable runs of over 35m between the satellite dish LNB and Sky box or Freesat receiver. Short cable runs of RG6 (20 metres or less) will show insignificant difference in performance.
The satellite coaxial cable featured above can also be used for TV aerial installation, as well as Freeview TV and Sky distribution systems including being suitable for cabling a loft distribution amplifier.
Important Note: The outside diameter of digital coaxial cables varies - 7mm cable clips should be used to secure WF100 coaxial cable and 6.4mm clips for RG6 cable. F-connectors are available in both diameters to suit RG6 or WF100. Both types of cable clip and F connector are available from Amazon to buy online.
It is generally cheaper to buy digital coaxial cable on a 100m reel (drum) if you have significant TV aerial or Sky installation work to undertake.
The technical specifications of the coax cables featured above are as follows:
PF100/WF100 Coaxial Cable
Signal loss of 0.18dB per metre at 860MHz (TV applications) - or 18dB per 100m
Signal loss of 0.3dB per metre at 2150Mhz (satellite installations) - or 30dB per 100m
RG6 Coaxial Cable
Signal loss of 0.21dB per metre at 860MHz (TV applcations) - or 21dB per 100m
Signal loss of 0.32dB per metre at 2150MHz (satellite installations) - or 32dB per 100m
