The sleeve antenna can be considered as a ground plane antenna whose very large number of radians has been folded along the coaxial cable to form a tube
Antenna is just a 1/4 wavelength resonator for both UHF and VHF band
This antenna is just a 1/4 wavelength resonator for both UHF and VHF band. It provides no GAIN as compared to other multi-section design
