NOTE:•••

This antenna is a mature product. The reason for only providing simulated data can be found in the following blog here.
Test data provided is collected from a sample lot. Actual data may vary slightly from unit to unit. All testing is performed
under +25 °C room temperature.
Eravant reserves the right to change the information presented without notice.

CAUTION:•••Any foreign objects in the antenna will cause performance degradation and possible device damage.
For 1 mm connectors proper torque should be applied: 4.0 ± 0.15 inch-pounds (0.45 ± 0.02 Nm). Torque wrench model
SCH-06004-S1 is highly recommended.
For 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, and SMA connectors proper torque should be applied: 8.0 ± 0.15 inch-pounds(0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly recommended.
