Length of wire between devices

[jacobsentertainment]

Hi all,

Not sure if this is the correct forum but giving it a try,
I am aiming at the next setup, an raspberry 4B with over usb an arduino mega, and hooked up to the arduino the Superheterodyne 433Mhz receiver/transmitter. Now I'm wondering what is the maximum length of wire I can run between the arduino and the 433Mzh modules. My goal would be 6 till 7 mtr. And next question would be what type of cable would be ideal for this task.

Thanks in advance.
