The Flann Standard Gain Horns have a wide range of applications, (e.g. as transmitting, receiving or sampling antennas or for feeding reflectors).

The absolute gain of a standard gain horn is calculable from the flare dimensions. Flann Standard Gain Horns are precision components providing accurate and repeatable gain references.

In general the lower frequency horns, models 06240 to 17240 inclusive, are accurately fabricated from brass sheet or aluminium. Models 18240 to 32240 inclusive are copper electroformed on precision mandrels which ensure high accuracy and repeat-ability. Typical gain/bandwidth curves are provided for all standard gain horns. 10 dB, 15 dB, 20 dB, 25 dB, 30 dB and 33 dB gain horns are also available in many waveguide sizes.

NB:- 25 dB models are approximately three times the overall length of the corresponding 20 dB models

 

Specifications:

Variation of mid-band gain with frequency …………………….. ± 2 dB
