4800–5000 MHz 9 dBi Gray Fiberglass Omni Antenna, N-Male, KSANT-11986-A

The 4.8–5.0 GHz band is where a growing share of public-safety and private 5 GHz radio traffic lands, and the demand for antennas that hold a clean omnidirectional pattern on a slim mast has never been higher. Network planners are constantly challenged to cover a campus, a depot or a public-safety site from one pole, on a band where clients move in every direction and there is nothing to aim at. The solution lies in a slim fiberglass omni that puts gain on the horizon and stays out of the way on the building. We are proud to introduce the 4800–5000 MHz 9 dBi Gray Fiberglass Omni Antenna, model KSANT-11986-A, a 600 mm linear-polarized radiator engineered for 4.9 GHz private and public-safety networks.

This antenna represents a practical balance between gain, physical size and finish. Its core advantage is the format: a single 600 mm radome of 20 mm diameter, weighing 0.24 kg, finished in gray and terminated in an integrated N-male connector. The band is covered from 4800 to 5000 MHz at 50 Ohm with VSWR <2.0, peak gain runs 8–9 dBi, and the horizontal pattern is a full 360°. Power handling is 50 W, the element is DC grounded, and the radome is rated for wind of 36.9 m/s across an operating range of −45 °C to +85 °C. It is the practical choice where one slim antenna has to cover everything that can see the pole.

Technical Excellence: The Core Advantage

The antenna's performance rests on three pillars: high gain concentrated on the horizon, a clean match across the band, and a slim build for real installations.

8–9 dBi with a 7–9° Vertical Beam

Peak gain is specified at 8–9 dBi, and the chamber measurements track it closely: 8.2 dBi at 4800 MHz rising to 9.2 dBi at 4980 MHz, with efficiency between 69.6% and 74.7%. The vertical beamwidth is 7–9°, deliberately narrow: the energy is concentrated into a flat disc on the horizon instead of spreading up into the sky and down into the ground. That is what turns a 600 mm radome into real horizontal reach, and it is the right pattern for sites where the users are on rooftops, yards and streets at roughly the same height as the mast.

A Clean Match from 4800 to 5000 MHz

The specified match is VSWR <2.0 across the band, and the stored trace marks 1.14 at 4800 MHz and 1.37 at 5000 MHz, with return loss of 23.7 dB and 16.2 dB at those two points. That margin keeps a 4.9 GHz radio at its top modulation step instead of dropping back because of reflections at the band edges. Impedance is 50 Ohm nominal throughout, so no matching section is needed between the antenna and the feeder.

A Slim 0.24 kg Radome with an N-Male Feed

The radome is 20 mm in diameter and 0.24 kg, so it can be carried up a ladder by one person and mounted on a wall bracket or a light pole. The finish is gray glass fibre reinforced plastic, which reads as infrastructure rather than as a product on a pole. Maximum power is 50 W, which is the honest figure for a small-cell or public-safety radio; this is not a 200 W macro-site product and should not be specified as one. The connector is an integrated N-male, the standard threaded interface on a mast, and the element is DC grounded so static charge drains to the mast rather than down the coax. Mechanical qualification is stated rather than assumed: a ≥20 N pull force 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 8–9 dBi, a slim 600 mm radome and a full 360° pattern makes this antenna useful wherever one pole has to serve users in every direction.

4.9 GHz Public Safety and Private Networks

Public-safety and private mobile networks: one omni covers a campus, a depot or a public venue without sector overlap, which is what a single-carrier 4.9 GHz site needs.

Campus and private LTE: industrial parks, ports and warehouses run private 4.9 GHz networks where users move in every direction, and a round pattern keeps handovers predictable around the site.

Outdoor Wi-Fi and WISP

Outdoor access points: one omni covers a courtyard, a parking lot or a yard without sector overlap, which is what a 5 GHz deployment needs at the lower band edge.

WISP subscriber nodes: the 8–9 dBi on the horizon gives usable margin at the edge of a 4.9 GHz cell, on a radome that mounts to an existing pole.

Roof and Pole Installations

Street poles and light masts: the 0.24 kg weight and gray finish suit wall brackets, parapets and light poles where a panel would look intrusive.

Temporary and event sites: the integrated N-male connector and light weight make the antenna quick to deploy and recover, which suits pop-up networks, construction sites and broadcast support.

Conclusion: The Future of Slim 4.9 GHz Omnis

The 4800–5000 MHz 9 dBi Gray Fiberglass Omni Antenna, KSANT-11986-A, is more than a passive component. It is the part that decides whether a 4.9 GHz site covers a campus or one corner of it. By covering 4800–5000 MHz at 50 Ohm with VSWR <2.0, concentrating 8–9 dBi into a 7–9° vertical beam, and carrying 50 W behind an integrated N-male connector on a 600 mm gray radome, it gives planners a footprint they can predict before the site survey. The 0.24 kg weight, 36.9 m/s wind rating and −45 °C to +85 °C operating range state its limits up front. For any 4.9 GHz deployment that needs one slim antenna to serve everything in sight, this antenna is the practical choice.
