Technical Description
Technical Specification(A) 2.5KW ANTENNA
Technical Specification(B) 5KW ANTENNA

TECHNICAL DESCRIPTION :

This is a quadrant antenna ideal for high power single channel Band III TV application. The coverage is basically Omni directional. There are 4 bays. Each bay is comprising of two radiating elements giving approximately 1.5 dB gain. Each dipole is mounted in V configuration. The dipoles are fabricated from the aluminum 1" wide 5mm thick flat.

A 1?" EIA connector is put at the bottom of the Aluminum Box. A two way power divider with impedance matching network having power handling capacity of 2.5KW/5KW put in side the main junction box to achieve better transformation of power form transmitter to air.

The total length of the antenna is 5.4 meter (max).

The antenna is designed for easy transportation in hilly area. Please refer figure No.1 for details.

The antenna is manufactured to provide long-term reliability and high performance. It is factory tuned for specific channel & assembled for easy installation at site.
