RG-59. Not used much any more.

coaxial cable
The signal loss in a RG59 75 ohm coaxial cable should be of no concern unless you are running over a couple hundred feet. In that case use RG 6.
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.
Max efficiency of energy transfer can only occur when impedence source matches the impedence of the load.
transfer impedance is impedance we encounter when an electrical current passing through one element of the system makes a voltage difference in other element of same system. eg:shield in a coaxial cable
A buffer amplifier can be used to transform high input impedence to low output impedence, or vice-versa.
Resistance divided by impedence
co-axial cable is used in tv and sattelite aerial communication also in cctv communication normally 50 ohms or 75 ohms impedence and normally terminated into BNC (BRITISH NAVAL COMMUNICATION) male and female conectors a crimping tool is used to do this job
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
Yes, you can plug an electric guitar into an acoustic amplifier. But I would suggest that you don't play at a high volume for a long period of time of the difference in impedence - an acoustic guitar (and bass and vocals) is low impedence, where an electric guitar (& keyboard) is high impedence.
