3 Answers. Sure, you can use 75 ohm coax instead of 50 ohm. In some cases (such as feeding a dipole), 75 ohm coax may be a better match to the load than 50 ohm. In other cases (such as feeding a vertical), it may be a worse match.Jun 23, 2019
What is the difference between 50 and 75 ohm cable?
It refers to the amount of resistance compared to the flow of electrical energy. A 50-Ohm cable will provide a better result than a 75-Ohm cable. This means that you will achieve better performance from your installs with a lesser Ohm "number".Mar 19, 2018
What is a 75 ohm balun?
What is a 75 to 300-ohm matching transformer? ... Impedance matching transformer is also known as balun is an electronic device that can transform a balanced signal or frequency to an unbalanced frequency signal. A 75 to 300-ohm matching transformer covers a balance 300-ohm signal to an unbalanced 75-ohm signal.
What is the difference between 50 Ohm and 75 Ohm?
In short, cables are measured by impedance, how much resistance there is to the flow of electrical energy. The smaller the Ohm, the better the performance. So a 50 Ohm cable provides much better results than a 75 Ohm cable.Jan 23, 2019
What is 75 ohm cable used for?
Cables with 75 Ohm are mostly used for video signals, while 50 Ohm cables tend to be used for data and wireless communications. In coaxial cables, Ohm refers to the impedance, which is the measure of resistance in the cable to the flow of electrical energy.
