The custom-designed N5-X modular antennas are specifically optimized for C5x extended frequency support. Each antenna in the N5-X family is optimized to isolate noise with incredible sidelobe rejection. The C5x's native 8 dBi gain can be increased to 12, 16, 20, or 25 dBi using Mimosa's modular N5-X twist-on antennas. Offering the ease and simplicity of integrated radios, but with so much more flexibility. Gain: 20 dBi Polarization Dual-slant 45 Dimensions: Diameter: 270 mm (10.63") / Depth: 83 mm (3.27").
