Many decades ago Bell Laboratories tested thousands of different coaxial cables and discovered that 75 ohm coax was the lowest attenuation impedance of all and was therefore ideal for receiving purposes
They also found that 30 ohm coax was the best for power handling and was therefore best for high power transmitters
50 ohm coax is a COMPROMISE between the superior loss specs of 75 ohm coax and the superior transmit power handling of 30 ohm coax
Since no scanner ever manufactured transmits RF, why isn't everyone using the Bell Laboratories proven best feed line for receivers?
