Yagi identifier notation:

YBN = with standard Dipole (Straight Split or Folded), GTV = with bent Dipole
n = narrow-band version; m = of medium band width, w = wide-band version, z is for low impedance Z, an added LT (in tribute to the EF0210LT by YU7EF) stands for exceptionally low Antenna Temperature
