You mean physically lengthen the wire. Unfortunately, the added horizontal radiation may defeat the intended purpose.  Ir pays to model.

The reason to use a series capacitor is to electrically lengthen the

the feed point would be 50 ohms, without a transformer that could
limit bandwidth somewhat.
