In radio-spectrum terminology for communications engineering, which named frequency band is widely used for television broadcasting and many low-power microwave applications?

Introduction / Context:
The radio spectrum is divided into standardized bands with typical applications assigned to each. Understanding which band supports broadcast television and many short-range microwave links is essential in networking, wireless design, and regulatory planning (e.g., antenna selection, link budgets, and interference analysis).

Given Data / Assumptions:

• We seek the named frequency range that fits television transmission and low-power microwave uses.
• Band names follow ITU/IEEE conventions.
• Options list canonical numeric ranges in MHz.

Concept / Approach:
Ultra High Frequency (UHF) spans 300 MHz to 3000 MHz (0.3–3 GHz). Broadcast TV allocations occupy portions of UHF (and historically parts of VHF). Many short-range microwave, cordless, and ISM applications (e.g., 433 MHz, 868/915 MHz, 2.4 GHz) are also in UHF. Super High Frequency (3–30 GHz) covers higher-frequency microwave and satellite bands, but the question emphasises TV and low-power microwave, which commonly reside in UHF.

Step-by-Step Solution:
Match “TV broadcasting + low-power microwave” to band usage patterns.Recall UHF numeric limits: 300–3000 MHz.Select the option that states this range explicitly.

Verification / Alternative check:
Digital terrestrial TV (DTT) channels operate widely in UHF. Wi-Fi at 2.4 GHz, Bluetooth, and many ISM devices also sit within the UHF boundary (upper end), illustrating the band’s relevance to “low-power microwave-like” consumer applications.

Why Other Options Are Wrong:
Very Low Frequency and Medium Frequency are far too low; they are used for long-wave, AM broadcast, maritime, and navigation services.

Super High Frequency begins at 3 GHz; many TV allocations and low-power consumer radios fall below this threshold.

None of the above: Incorrect because UHF is the well-known answer.

Common Pitfalls:
Confusing the terms “microwave” broadly (often >1 GHz) with the specific named bands; although some microwave definitions overlap with UHF, TV and numerous low-power devices live squarely in UHF.

Final Answer:
Ultra High Frequency: 300 MHz to 3000 MHz
