Twist-on modular dish antenna adds 20 dBi gain to C5x radios across 4.9–6.4 GHz with dual-slant 45 polarisation and strong sidelobe rejection
- 20 dBi gain extends C5x range for long-distance links
- Dual-slant 45 polarisation improves signal isolation in noisy environments
- Twist-on modular design enables quick antenna swaps without tools
- Optimised for 4.9–6.4 GHz extended frequency support on C5x radios
- 250 mm dish diameter focuses beam for high sidelobe rejection
Modular Twist-on Antenna for C5x
The Mimosa Networks N5-X20 is a 250 mm modular dish antenna that raises the C5x radio's native 8 dBi gain to 20 dBi. It operates across the 4.9-6.4 GHz band and uses a twist-on mechanism for quick attachment. Each unit provides dual-slant 45 polarisation and strong sidelobe rejection to isolate noise. The pack contains two antennas for deployment at both ends of a link.
Gain Upgrade from 8 dBi to 20 dBi
The C5x radio ships with an integrated 8 dBi antenna that can be increased to 12, 16, 20, or 25 dBi by adding an N5-X module. Choosing the 20 dBi version extends range and improves link quality over the 12 dBi and 16 dBi options while keeping the dish diameter at 250 mm. The jump is worth it when the extra margin is needed for longer paths or higher interference environments without stepping up to the larger 25 dBi model.
Point-to-Point Links Needing 20 dBi Gain
These antennas suit installers building point-to-point links with Mimosa C5x radios who require 20 dBi gain and dual-slant polarisation in a 250 mm form factor. They are not for users who need the higher 25 dBi gain option or a different dish size. They are also not for operators using radios other than the C5x, as the twist-on mount and frequency optimisation are specific to that platform.

Questions about this item
Will the 270 mm diameter dish fit on my existing C5x radio mount?
The antenna measures 270 mm in diameter and 83 mm deep, so verify your mount can accommodate a 10.63 inch wide by 3.27 inch deep dish before ordering.
How do I attach the twist-on antenna to the C5x without damaging the connector?
Align the modular twist-on base with the C5x radio interface and rotate clockwise until it locks; the keyed design prevents cross-threading if you do not force it.
When should I replace the antenna if the sidelobe rejection degrades over time?
Physical damage, corrosion on the twist-on threads, or a measurable drop in the 20 dBi gain are the practical indicators that the antenna needs replacement.
