After using differant cables for the last 30+ yrs, here is my take.
Any thing up to 2ft, I use RG214, up to 50 ft RG58, up to 150 RG 6 OR RG 8, all this for both RX and TX up 500 watts, HF VHF UHF.
Over 150 ft (I have three) I use hard line either 50 ohm helix or cable co. type 75 ohm.
I have never had any problems recieving or transmitting on any frequency.
Frequency's that I use/listen to go from 500hz to 900mhz.
