Adrian: Doing this comprises shielding integrity. This would seem to be asking for leakage, unless the cable termination inside the radio was very close to where it exits the radio and there is a very close connection between the shield connection point and the chassis where the cable exits. I've seen some radio manufacturers do this and it's never a good idea.
The same problem applies to the power connection, which is more difficult to deal with in this respect. In effect, any stray RF inside the radio that can couple to any conductor that exits the radio without proper RF bypassing or shielding is a problem. (Question: How many RF power amplifiers are built this way?) Of course this also applies to RF ingress.
