Thanks to you David and all for the ideas you've given me. I may built something or look hard at one of the commercial products out there. Take care all and very 73.

Drill 4 holes at quadrants in the washer. Solder 1/4 wave radials to it, put over chassis mount BNC socket and fix with fixing nut. Solder 1/4 wave wire to centre conductor (not the bus conductor!). It will scrunch up into a bag as it is so flexible and sits neatly on a baggage rack. 73 de G3YXX
