The Y415S-D (Stainless Steel) is a 14dBd gain, 15 element UHF yagi antenna. It covers the entire range from 480 MHz to 520 MHz. It is supplied with a standard boom length and is DC grounded and fully welded for lightning protection and noise reduction.
Whilst the installation of our UHF yagi is normally a straight forward exercise, the following guide lines are to ensure that the maximum reliable service life is obtained whether aligned for Horizontal or Vertical polarization.
- The yagi cable tail is a critical length and should never be changed. If the cable or connector sustain any damage we recommend that the yagi be returned to JBA Antennas for repair.
- After connection of the feedline to yagi we recommend using self-vulcanizing tape to seal the coaxial connectors against the ingress of moisture.
- When mounting the yagi for Vertical Polarization it is important to ensure the condensation drain hole in one end of the yagi dipole element is facing down.
- When mounting a yagi for Horizontal Polarization the dipole mounting block should face down as condensation drainage is via the coaxial cable entry hole.
