Aerial co.ax. cable?
:confused: Hello. I want to fit an FM aerial on the roof of my house. I can fit it where I used to have a Sky digital dish. (i no longer subscribe to Sky) What I want to know is can I utilse the cable (standard stuff as fitted by Sky installers) that used to take the signal from Sky dish to Sky box to save me running in a new cable. Is it OK for an FM signal. Anybody know? Thanks, Gerry

Re: Aerial co.ax. cable?
if you are referring to FM radio then you will require 50 ohm cable

75ohm coax and 300ohm flat twin are the only FM connections I have ever seen.

Re: Aerial co.ax. cable?
I agree that it should be 75 ohms - all FM aerials are matched to this impedance so it makes sense that the input to the tuner is designed to match this.

"Most common coaxial cable impedances in use in various applications are 50 ohms and 75 ohms. 50 ohms cable is used in radio transmitter antenna connections, many measurement devices and in data communications (Ethernet). 75 ohms coaxial cable is used to carry video signals, TV antenna signals and digital audio signals. In addition, this was extracted from the Quad FM4 Tuner handbook. Quad should know!! FM4 Spec.jpg |
