Short answer: If you want free local broadcast channels alongside streaming, use an over‑the‑air aerial; if you only use streaming services, an external aerial is optional. For urban points within 10–20 miles of transmitters a compact indoor amplified loop (2–5 dBi) usually suffices; suburban locations up to ~35 miles benefit from a directional UHF/VHF antenna (6–12 dBi) mounted 15–30 ft above ground; distances beyond ~35–60 miles call for a rooftop Yagi/log‑periodic (10–16+ dBi) plus a low‑noise masthead preamplifier.
Frequency and tuner notes: local broadcasters operate on VHF low (roughly 30–88 MHz), VHF high (174–216 MHz) and UHF (470–700+ MHz) bands under ATSC standards in the U.S.; check your set’s onboard tuner (ATSC 1.0 or ATSC 3.0) and the station list for channel band allocation before selecting equipment. Use online signal maps (FCC DTV maps, TV Fool) to get azimuth and estimated signal strength in your address; pick an aerial type that matches the transmitter azimuth and band mix.
Cable and amplification specifics: use RG‑6 quad‑shield with F‑type compression connectors for runs under 50 ft. Expect cable loss rising with frequency (approximate order of magnitude: ~1 dB/100 ft at low VHF, ~2–3 dB/100 ft at mid‑UHF, ~5–7 dB/100 ft at high UHF – exact loss depends on cable grade). Masthead preamps typically provide 12–18 dB gain with noise figures around 0.5–1.2 dB; install the preamp at the antenna if run length or weak signals justify it. Avoid indoor distribution amplifiers in strong‑signal areas because overload can cause picture breakups.
Placement and setup workflow: mount the aerial as high and as clear of obstructions as practical; point directional units toward the dominant transmitter azimuth provided by coverage tools; perform an auto‑scan on the set after every position change. If multipath or missing channels appear, try ±10–20° rotation and small vertical adjustments. For multisite reception (transmitters at different azimuths) consider a wide‑band log‑periodic or two‑antenna combiner with proper filtering.
Quick actionable checklist: 1) Run an address lookup on FCC DTV maps or TV Fool; 2) Choose indoor loop for <~20 miles, directional roof mount for ~20–35 miles, high‑gain rooftop for >35 miles; 3) Use RG‑6 with F‑type compression connectors; keep cable runs short or use masthead preamp; 4) Scan the tuner after each change; 5) If reception is marginal, raise the mount height or upgrade to a higher‑gain rooftop aerial and a low‑noise preamp.
Prefer wired Ethernet for highest stability: use Gigabit (1000BASE-T) or faster; reserve Wi‑Fi for convenience or secondary use.

Quick diagnostics checklist:
Inspect the rear/side panel and the spec sheet: an RF/coax connector labeled "ANT IN", "AERIAL", "RF IN", "TERRESTRIAL" or "CABLE" plus a spec line such as "Tuner: DVB‑T/T2", "ATSC 1.0/3.0", "ISDB‑T", "DVB‑C" or "DVB‑S/S2" indicates an integrated tuner capable of receiving over‑the‑air or cable/satellite signals.
Exact verification steps: 1) locate the model number on the sticker (example format: XX‑1234); 2) search " specifications tuner" or " DVB-T2 / ATSC / ISDB-T" in the manufacturer website or retailer spec page; 3) open the downloadable user manual and jump to "Connections" and "Channel setup" sections to confirm supported standards and connector labeling.
Regional standard quick reference: United States – ATSC 1.0/3.0 (terrestrial/cable QAM separate); Europe – DVB‑T/T2 for terrestrial, DVB‑C for cable; Japan/Brazil – ISDB‑T; Satellite reception typically lists DVB‑S / DVB‑S2 and shows an "LNB IN" or "SAT" coax input. Match your country to the standard listed in the spec to ensure compatibility.
Software check: open Settings → Channels / Broadcasting → Auto‑tune or Channel Scan. If the menu shows terrestrial/cable/satellite options and lets you start a scan, a tuner is present. If those options are absent, the unit lacks an integrated tuner or the firmware does not expose it.
If no tuner is present or the model supports different regional standards than yours, options include: an external set‑top receiver (ATSC/DVB‑T2/DVB‑C/DVB‑S box), a USB tuner dongle that explicitly lists compatibility with the device's operating system, or a cable/satellite provider box. For USB receivers, verify driver/OS support on the manufacturer page and use a powered USB hub if the stick requires extra current.
Final checks: look for "Tuner" or "Reception" in the official spec sheet, confirm connector labels on the chassis (RF vs LNB have different uses), and update the device firmware before rescanning channels since tuner firmware updates and regional channel lists are sometimes delivered via system updates.
