About a simple Bulkhead-Entry-Point. A success at lowering man-made local noise for me. This is a simple solution I use successfully at home: https://www.flickr.com/photos/pa5mw/28796976750/in/album-72157667970861390/

Is this purely for static and lightening protection purposes or does it also help mitigate Common Mode problems as well? If feedlines are well grounded, are chokes still useful for controlling Common Modes problems? I suspect that both can be used, and should be used, in a well designed station. Are there specific recommendations on the use of chokes on grounded feedlines? Does placement matter?
