Direct 21-5G

Directional parabolic antenna working in 5 GHz band. There is a possibility to use Direct 21-5G in horizontal polarization or vertical polarization. Antenna is made of a top quality two-layer ABS/Plexiglas (PMMA) material which enables Direct 21-5G to be used also in more difficult climatic conditions. The antenna is corrosion resistant and its lifetime is very long. The weight of Direct 21-5G is very low (up to 0,69KG).

Feeder

Feeder

Direct 21-5G has a new feeder (half wave’s dipole in waveguide). Coaxial waveguide which is ended with N connector is completely hidden in the holder of feeder. Feeder’s collar is shaped exactly according to the type of parabolic reflector. After this manner optimal radiation is secured. Moreover, maximum possible gain is achieved and possible over radiation of reflector
is eliminated.
