What is a 75 Ohm coaxial cable?
The 75 Ohm impedance is a world-wide accepted value for all kinds of coaxial high frequency signal connections. Impedance is another word for the value of electrical resistance for alternating current: An alternating voltage applied at one cable end results into an alternating current flowing into the cable.
Is RG-6 50 Ohm or 75 ohm?
So a 50 Ohm cable provides much better results than a 75 Ohm cable. Most home cell phone signal boosters come in 75 Ohm systems with 75 Ohm cables such as RG-6 with F-connectors. Most commercial cell phone signal boosters come in 50 Ohm systems with 50 Ohm cables such as LMR400 with N-connectors.

Is it OK to use 75 ohm coax?
And a directional antenna in a receive application fed with coax with poor isolation may pick up enough external noise to negate the benefits of the antenna directivity. 75 ohm coax will work, and you may be able to find good quality 75 ohm coax at a favorable price. But do try to make an informed decision.
Can you feed RG-6 with 50Ω coax?
Feed a resonant dipole with 50Ω coax, and you actually have a small mismatch! The power handing capability of RG-6 is almost identical to RG-213. And even at the legal limit, the voltage is still low enough that flashover will not occur between the center conductor and the shield even with a mismatch.
Can you use RG-6 cable as a transmitter?
VHF/UHF is another story. RG-6 is rated for applications below 150 MHz, so it can be used with transmitters and antennas on the 2 meter band. but above the frequency, the losses are going to be so high, that you might as well invest in quality 50 Ohm cable.
Can a 75 ohm cable be used with a 50 ohm antenna?
You can use these cables with a 50 Ohm amateur radio antenna system, but because of the impedance mismatch, your SWR will be a little higher. For example, if everything else is balanced out, using the 75 ohm cable with a 50 Ohm antenna will increase your SWR to 1.5:1 at the transmitter.
