Antenna Coverage: What You Actually Need
4G IoT antenna minimum: 700-2700 MHz. This covers Band 28 (700 MHz), Band 20 (800 MHz), Band 8 (900 MHz), Band 3 (1800 MHz), Band 1 (2100 MHz), and Band 7 (2600 MHz). Every UK 4G band for every operator.
4G + 5G IoT antenna minimum: 700-3800 MHz. This adds n78 (3500 MHz) and n28 (700 MHz) 5G NR coverage on top of all 4G bands. This is the specification to use for all new IoT hardware designs in 2026.
For specific antenna products covering these ranges, see 4G antenna selection and 5G antenna selection.
Frequently Asked Questions
Which 4G band is most important for UK rural IoT deployments?
Band 20 at 800 MHz. It has the best building and terrain penetration of any UK 4G band and is available from all four major operators. Band 28 at 700 MHz is even better for penetration and is being deployed by EE and Three — coverage is expanding but not yet as comprehensive as Band 20. Any rural UK IoT antenna must cover 700-900 MHz.
What is the minimum frequency range for a UK IoT antenna?
For 4G only: 700-2700 MHz covers all UK LTE bands. For 4G + 5G: 700-3800 MHz covers all 4G and 5G Sub-6GHz bands in use in 2026. Antennas labelled 617-5000 MHz or 698-4000 MHz provide future-proofing. An antenna that only covers 800-2100 MHz is missing Band 20 low edge, Band 3 high edge, and all 5G n78.
Do I need to worry about band steering on my IoT router?
Band steering is primarily a WiFi term. For cellular IoT, the equivalent is band locking or preferred band configuration. Some industrial routers (Teltonika, Peplink) allow you to lock to specific bands. This is useful when you know your deployment is best served by Band 20 (rural) or Band 3 (urban) and want to prevent the modem from connecting on a weaker band first.
