Note:• This antenna is a mature product. The reasons for only providing simulated data can be found in
the following blog here.
• All testing was performed under 25˚C room temperature.
• Eravant reserves the right to change the information presented without notice.
Caution:• Any foreign objects in the horn antenna will cause performance degradation and possible device
damage.
• Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.05 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
