ANT-2.4-CW-RCT-xx DATA SHEETS Product Dimensions Description The RCT 1/2-wave 2.4GHz antenna delivers outstanding performance and orientation flexibility in a compact physical package. The antenna’s innovative articulating base allows it to tilt and swivel for optimum orientation. The RCT mounts quickly via an SMA or FCC Part 15 compliant RP-SMA connector. 0.39” (10.0) 4.44” (113.0) Features Tilts and rotates Very low VSWR Excellent performance Omni-directional pattern Fully weatherized Rugged and damage-resistant RP-SMA or SMA connector 3.76” (95.6) Electrical Specifications Center Freq.

This does not mean that your product must conform to this size or antenna orientation, although it should be recognized that the gain, pattern, and performance may increase or decrease accordingly. Antenna Factor recognizes that our antennas are often used in compact applications with less than ideal ground planes. In some cases, the reference jig is smaller than optimum, particularly with lower-frequency antennas. This is, in part, to more accurately reflect the performance of the antenna in typical real-world applications. 4.00” (101.6) GROUND PLANE ON BOTTOM LAYER Antenna Factor 575 S.E.
