Descriptions of different versions of YAGI antennas

YAGI antennas are machanically very strong, suitable for locations with strong weather influence (e.g. snow, ice). Mechanically are assembled by:

1) Main antenna carrier: aluminium tube 18x18 EN AW 3005 (AlMn1Mg0,5) H165 or
2) Main antenna carrier: aluminium tube 18x12 EN AW 3005 (AlMn1Mg0,5) H165
3) Iron parts: hot galvanized steel
4) Fixing to mast:
"U" screw M6, inclination 0-10°, horizontal or vertical polarization, outside mast diameter D=20...62mm
5) Plastics: ABS, UV resistant








 

Each YAGI antenna has different electrical characteristics, so it is possible to select suitable antenna for various locations.

All YAGI antennas have impedance je 75 Ohm.

Dipole

Dipole is the heart of antenna. Therefore, each dipole of YAGI antenna is designed for the best signal reception on its frequency band.
YAGI antennas have mechanically 3 different dipoles:

• Classic dipole direct connection of coax. cable
• Classic dipole with “F” female connector

• DTX dipole (with “F” female connector only)
  The DTX dipole is especially designed for the digital terrestrial signal's (DVB-T) reception.
  
  
   

Directors

Directors are different shapes, dimensions and electrically specially designed for each antenna’s type:

• Channel and VHF antennas
  tubes with outside dia. 10 mm, premounted. Final mounting without any tools.
• DTX series antennas
  rods dia. 4 mm, final mounting without any tools.
• DTM series antennas
  tubes with outside dia. 8 mm, fixed on antenna carrier, additional mounting is not needed.
• TRIPLEX in UF series antennas
  rods dia. 4 mm, fixed on antenna carrier, additional mounting is not needed.

Reflectors

All reflectors are already factory-assembled.
Each antenna's reflectors are adjusted to achieve the best possible characteristics for the antenna.
Reflector’s installation on the antenna carrier is quick and easy without additional tools.
