It has to be long enough to dissipate some energy from the 
Clipperton's cathode. It terminates the input of the PA by 
presenting a somewhat low impedance on every frequency around 
ten meters, and absorbs and dissipates a little bit of the unwanted 
feedback from anode back to cathode.

Every little thing helps when the amp is on the edge of stability. 
The problem is on some frequency, the radio no longer looks like 
any kind of load for the input, so feedback can get pretty high.
