WR-28 Pyramidal Horn Antenna, 17 dBi Gain with 2.92 mm Coax Input, Weather ResistantCaution:• Any foreign objects in the horn antenna will cause performance degradation and possible devicedamage.
• Proper torque, 8.0 ± 0.4 inch-pounds (0.90 ± 0.02 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
