Default Shortened radials: which length?

I was wondering if it's possible to shorten the radials from the standard
1/4 wavelength to another value, a smaller one. For example, in a 20 meters
antenna, which is the best value of length for shortened radials or, in
alternative, until which value is possible to go to without superlosses?
Thanks in advance

E il marconista sulla sua torre,
le lunghe dita celesti nell'aria,
riceveva messaggi d'auguri
per questa crociera straordinaria.
E trasmetteva saluti e speranze
in quasi tutte le lingue del mondo,
comunicava tra Vienna e Chicago
in poco meno di un secondo.
E la ragazza di prima classe, innamorata del proprio cappello,
quando la sera lo vide ballare lo trovò subito molto bello.
Forse per via di quegli occhi di ghiaccio così difficili da evitare,
pensò "Magari con un po' di coraggio, prima dell'arrivo mi farò
baciare".

Francesco DeGregori
