The cordless phone using this type of antenna is communicating more than 20-30KM here. Its main engine is 2sc1971. So I think It is directional and better than vertical dipole.may be has higher gain. Any details... do you have?
It is a 1/4 lambda vertical driven element with a radial ground-plane. Slight amount of onmi-directional gain over isotropic. This one is resonant on three different bands; each vertical rod resonates on a different frequency.
