This is not true. Many types of antenna systems are "efficient radiators" off their resonant frequency. Rather than go into a long discussion here I will refer to this post by Owen Duffy because he has detailed examples.
From his article
"It is often that one hears in QSO, one OM to another, describing their antenna and stressing the importance of >>resonance, almost as qualification that if the antenna is resonant, then it performs well, and that by implication a
non- resonant antenna has poor performance.
Whilst the importance of resonance is often parroted on the bands, reputable texts do not seem to echo the sentiment."
