I too would agree with what has been said, it can be so easy to forget the scenario of a possible live chassis, even for the long time experienced. If fitting blocking capacitors then don't forget that capacitors have an impedance so far as AC is concerned, the higher the value of capacitance then generally the lower the impedance at any given frequency. So far as your aerial goes Rob it depends what you want out of your radio, for MW reception then a frame or loop aerial takes some beating, but for SW an outside long wire as high and clear as you can get it is prefferable.
Never earth a receivers chassis if the receiver is of the AC/DC type unless it is run from a fully isolated supply eg: a suitably rated isolating transformer.
