moaning about which ever choice of fixing to me is a load og bollox
BUT, why you say 'why do you think' FP is only suitable for CB systems' the fact is, the regs used to say that.
We do not dream up why certain cables are used, do you not have a copy of the BS regs.
To say FP can ONLY be used on CB systems is bollox, but it used to be the genberal jist of BS regs.
