480-520MHz Aluminium Yagi – 9 Element

Part # Y49-D. Categories: , , . Tags: , , , , , .


The Y49-D (Aluminium) is a 12dBd gain, 9 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.

  1. 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.
  2. After connection of the feedline to yagi we recommend using self-vulcanizing tape to seal the coaxial connectors against the ingress of moisture.
  3. 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.
  4. When mounting a yagi for Horizontal Polarization the dipole mounting block should face down as condensation drainage is via the coaxial cable entry hole.
