600-7200MHz Ultra Wideband Flat External Rubber Antenna WiFi 6E SMA Jack KSANT-11492-A

A modern gateway has to serve 5G sub-6, WiFi 6E and a legacy low band, often on one radio card. Putting one antenna on each band fills the case with connectors and cables. The demand for a single wideband rubber antenna that runs from 600 MHz to 7.2 GHz has never been higher. Designers are constantly challenged to keep one part useful from the low band up to 7 GHz, where a narrow whip would only hold one band. The solution lies in a flat rubber antenna with a wideband element. We are proud to introduce the 600-7200MHz Ultra Wideband Flat External Rubber Antenna, model KSANT-11492-A.

This part answers a wideband terminal requirement. One part covers 600 MHz to 7200 MHz, so a single connector serves the low band, 2.4 GHz, 5 GHz and the 6 GHz WiFi band. The datasheet states two sets of limits for the same span: between 600 and 960 MHz the peak gain is 1.3–3.6 dBi, VSWR is below 2.5, and efficiency is about 55%; between 1000 and 7200 MHz the peak gain is 0–4.6 dBi, VSWR is below 4.0, and efficiency is about 58%. Polarization is linear, the horizontal pattern is 360° with a vertical beam of 31–45° in the low band, impedance is 50 Ohm, and maximum power is 50 W. The body is 20×145 mm flat black rubber, the connector is SMA-J, and the weight is 0.015 kg.

Technical Excellence: The Core Advantage

The antenna works on three points: continuous coverage from 600 MHz to 7.2 GHz, a flat body that fits a small case, and a tested mechanical build.

Continuous Coverage from 600 MHz to 7200 MHz

One part covers the whole span without a gap in the middle. A gateway with a low band radio, 2.4 GHz WiFi, 5 GHz WiFi and 6 GHz WiFi needs one antenna hole instead of four. The two sets of limits in the datasheet are there because a wideband element behaves differently at the bottom of the band: below 960 MHz VSWR stays under 2.5, and above 1000 MHz it stays under 4.0. Both are stated, and both apply to the same antenna.

A Flat Body That Fits a Small Case

The body is 20×145 mm and flat, not round, so it sits against a housing or a panel without a large cutout. The weight is 0.015 kg, the lightest part in this series, so a portable gateway or a camera does not feel it. The horizontal pattern is 360°, so the unit does not have to be aimed, and the vertical beam is 31–45° in the low band and wider at the top, which is what a wideband element does.

A Build That Was Tested, Not Just Drawn

The part has been through storage at −45 °C to +85 °C, five cycles of high and low temperature, damp heat at 95% relative humidity, vibration from 10 to 55 Hz, a 1 m drop test, a pull force test at 20 N or more, and a withstand voltage test at 1.5 kV. The working range is −40 °C to +80 °C, storage is −45 °C to +85 °C, and humidity is under 95%. These are the tests a buyer should ask about on a rubber antenna that leaves the case every day.

Versatile Application Scenarios

Wideband coverage, a flat body and a 0.015 kg weight make this rubber antenna useful wherever a small terminal has to work on several bands at once.

Sub-6 GHz 5G CPE and Routers

5G CPE and indoor routers: one part covers the low band and the sub-6 5G range, so the case keeps one antenna port.

WiFi 6E access points: the band runs to 7.2 GHz, which covers the 6 GHz WiFi range as well as 2.4 and 5 GHz.

Multi-Band IoT and Camera Gateways

IoT gateways: a unit that has to talk on 900 MHz, 2.4 GHz and 5 GHz at once needs one wideband part, not three.

Cameras and monitoring units: the flat body sits against the housing, and the 0.015 kg weight does not load a small bracket.

Test, Measurement and Public Safety Radios

Bench and field test kits: a 600–7200 MHz part covers almost every band a technician meets in one day.

Public safety and utility radios: the low band covers 600–960 MHz land mobile channels, and the upper span covers the data link.

Conclusion: One Part for the Whole Band Plan

The 600-7200MHz Ultra Wideband Flat External Rubber Antenna, KSANT-11492-A, does one job: it covers one span from 600 MHz to 7.2 GHz on one connector. The 20×145 mm flat black body carries a wideband element with 1.3–3.6 dBi and VSWR <2.5 below 960 MHz, and 0–4.6 dBi with VSWR <4.0 from 1000 to 7200 MHz, at 50 Ohm, linear polarization and 50 W. Efficiency is about 55% and about 58%, stated as tested. The 0.015 kg weight, −40 °C to +80 °C range, and the drop, vibration and 1.5 kV withstand tests state the rest. For a compact terminal that has to cover 600 MHz to 7.2 GHz in one part, this rubber antenna is the practical answer.
