Hello everyone I am somewhat super confused.. Question: I am being told that I will need to use a 75 ohm to a 50 ohm adapter if I am using 75 ohm RG6 quad shield coax connected to a TRAM1411 antenna > scanner of which is 50 ohm, in order to make up for the mismatch in impedance. If any of you guys out there have any suggestions, I am open to all opinions/comments from the experts! Thanks.

If this is for a scanner, I wouldn't worry about it.
If you plan to transmit using RG-6, you will probably need to account for the impedance mismatch. Also, check the maximum power rating of your cable so you don't exceed it.
The most common connector for RG-6 is the F connector. You will need adapters at either end to connect the antenna and the scanner.

There are transformers that will match 50/75 ohms with very low loss but they cost more than your antenna.
Since you wrote
Is it safe to assume you are NOT transmitting with that antenna? If so, then there is no concern about the 50 to 75 ohm impedance difference for the scanner.
