Please have another pleasant read of the original post...
hinchy needs an antenna!
I think basically what he is trying to say is that he needs an antenna. Not wishing to award somebody for the honour of having read more brochures whilst in an office.
Further, and I can only guess here, but if he was not happy with the sounder, including its accuracy and yes its apparent 'refresh' rate, then hinchy would not be trying to buy a new antenna for it.
