5150–5350 MHz 8 dBi 360° Fiberglass Omni Antenna, 600 mm, Integrated N-Male, Elegant Black, KSANT-12390-A

The lower half of the 5 GHz band carries most of the outdoor Wi-Fi traffic that actually has to travel a distance, and the demand for an antenna that covers it evenly in every direction has never been higher. Network planners are constantly challenged to light up a marina, a campus quad or a rooftop without hanging four sectors and four runs of coax on the same mast. The solution lies in slim fiberglass omni antennas that put a round pattern on the horizon from a single mount. We are proud to introduce the 5150–5350 MHz 8 dBi 360° Fiberglass Omni Antenna, model KSANT-12390-A, a 600 mm vertical-polarized radiator engineered for outdoor access points, wireless bridges and 5 GHz fixed wireless links.

This antenna represents a practical balance between pattern roundness, physical size and finish. Its core advantage is the format: a single 600 mm radome at 25 mm diameter, weighing 0.22 kg, finished in elegant black and terminated in an integrated N connector. The band is covered from 5150 to 5350 MHz at 50 Ohm with VSWR <2.0, peak gain runs 7.3–8 dBi, and the horizontal pattern is a full 360° with roundness held to ±1.5 dB. Power handling is 200 W, the element is DC grounded for lightning protection, and the radome is rated for wind of 36.9 m/s. It is the practical choice where one slim antenna has to cover everything that can see the mast.

Technical Excellence: The Core Advantage

The antenna's performance rests on three pillars: a genuinely round horizontal pattern, vertical gain that stays on the horizon, and a feed and finish that survive outdoor life.

360° Coverage with ±1.5 dB Roundness

An omni antenna is only as good as its roundness, and this design specifies it at ±1.5 dB. The chamber report backs that up: measured roundness is 1.21 dB at 5150 MHz, 1.91 dB at 5250 MHz and 1.79 dB at 5350 MHz. In practice that means a client on the north face of the building gets substantially the same signal as one on the east, so capacity planning does not have to account for a pattern that quietly tilts in one direction. The vertical beamwidth is 7–9°, deliberately narrow: the energy is squeezed into a flat disc at the horizon rather than spread up into the sky and down into the ground, which is what turns a 600 mm radome into 8 dBi worth of reach.

7.3–8 dBi from a 600 mm Elegant Black Radome

Peak gain runs 7.3–8 dBi across the band, and the chamber measurements track it closely: 7.4–7.9 dBi from 5150 to 5350 MHz. The radiating element sits inside a 600 mm fiberglass radome of 25 mm diameter, finished in elegant black. That combination matters on real sites. At 25 mm the antenna reads as a slim whip rather than a panel, which is what allows it to be mounted on a wall bracket, a pole or a parapet without changing the look of the building. At 0.22 kg it can be installed by one person on a ladder. Glass fibre holds its shape and its electrical behaviour through UV, rain and the −45 °C to +85 °C operating range, and the black finish keeps the radome visually quiet on commercial façades. Rated wind velocity is 36.9 m/s, so the mechanical limit is stated rather than discovered.

VSWR <2.0, 200 W Handling and an Integrated N Connector

The specified match is VSWR <2.0 across 5150–5350 MHz, and the stored trace marks 1.29 at 5150 MHz and 1.41 at 5350 MHz, with return loss of 17.9 dB and 15.3 dB at those two points. That margin is what keeps a 5 GHz radio running at full modulation instead of dropping to a lower MCS rate because of reflections. Maximum power is 200 W, well above what an outdoor AP or a bridge delivers, so there is headroom for multi-carrier or amplifier-fed operation. The connector is integrated into the base rather than fitted as an adapter, which removes one mechanical joint and one source of passive intermodulation, and the radiating element is DC grounded so static charge drains to the mast instead of into the radio. Impedance is 50 Ohm nominal across the band, so no matching section is needed between the antenna and the coax. Efficiency is specified at 65%, with measured values between 58.5% and 78.3% across the band, and the assembly is qualified by a ≥200 N tensile test, a 1 m drop test, vibration from 10–55 Hz at 0.35 mm displacement and 50.0 m/s² over 30 sweep cycles, and voltage resistance of 1.5 kV insulation, 1.5 kV sheath and 0.5 kV insulation-to-sheath. The product is RoHS compliant.

Versatile Application Scenarios

The combination of a round pattern, 8 dBi and a 25 mm radome makes this antenna useful wherever one mount has to serve a wide arc of clients on 5 GHz.

Outdoor Wi-Fi and WLAN Coverage

Outdoor access points and hotspots: a single omni covers a courtyard, a pool deck or a park plaza without sector overlap, which is exactly what the 5150–5350 MHz allocation is used for in most regulatory domains.

Marinas, campuses and hospitality sites: the slim black radome mounts on an existing light pole or façade bracket, so coverage can be added without a new structure or a visible panel.

Fixed Wireless and Point-to-Multipoint

WISP subscriber and relay nodes: 8 dBi on the horizon plus a clean 50 Ohm match gives link margin at the edge of a 5 GHz cell, and the 200 W rating leaves room for amplifier-fed links.

Temporary and event networks: the 0.22 kg weight and integrated connector mean the antenna can be deployed and recovered quickly, which suits pop-up networks, construction sites and broadcast backhaul.

Surveillance and Building Backhaul

Wireless CCTV backhaul: cameras and video links at 5 GHz need steady throughput, and a round pattern keeps several camera drops on one antenna instead of one directional link per camera.

Cross-building links inside a campus: an omni at the hub and small directional units at the spokes is a simpler topology than point-to-point pairs everywhere, and it survives when a spoke moves.

Conclusion: The Future of Slim 5 GHz Omni Coverage

The 5150–5350 MHz 8 dBi 360° Fiberglass Omni Antenna, KSANT-12390-A, is more than a passive component. It is the part that decides whether one 5 GHz mount covers a site or just a corner of it. By holding roundness to ±1.5 dB across a full 360°, concentrating 7.3–8 dBi into a 7–9° vertical beam, and carrying 200 W into a DC-grounded element through an integrated N connector, it gives planners a footprint they can predict before the site survey. The 600 mm radome at 25 mm diameter and 0.22 kg keeps it discreet and easy to install, while VSWR <2.0, a 36.9 m/s wind rating and a −45 °C to +85 °C operating range state its limits up front. For any 5 GHz outdoor deployment that needs one slim antenna to serve everything in sight, this antenna is the practical choice.
