MyGica A681 Setup Guide: Free Over-the-Air TV in Canada 2026

Published May 2026 — written by the FTA TRONIX team in Ottawa, tested with antennas at 8 km, 35 km, and 110 km from the Camp Fortune transmitter.

Free over-the-air television is the savings most Canadian households forget exist. CBC, CTV, Global, CityTV, Omni, TVO, ICI Radio-Canada — all broadcasting in 1080i HD, all completely free, all you need is a $40 USB tuner and a decent antenna. The MyGica A681 USB ATSC HDTV tuner is the easiest way in. This guide walks you through plugging it in, scanning channels, troubleshooting weak signals, and pairing it with your existing streaming box for a Plex DVR setup that holds its own against any paid service.

Why over-the-air TV still matters in 2026

Over-the-air broadcast TV doesn't get talked about much anymore, but it's quietly the best value in Canadian television. Plug an antenna into a $40 USB tuner and you'll pull a dozen or more local channels — CBC, CTV, Global, CityTV, Omni, TVO, ICI Radio-Canada — in HD, with zero monthly fee, forever.

Live sports save the format. Hockey Night in Canada, the Grey Cup, the Olympics, NFL games on CTV, World Cup coverage — all available free in real-time, with no app login, no IP throttling, and no buffering during the third period. The picture quality is genuinely surprising: uncompressed 1080i over-the-air feeds often look noticeably better than streaming services delivering the same channels, because there's no second compression pass.

Over-the-air also pairs perfectly with a Formuler Z12 Ultra or Dreamlink Dlite+ 5G for a full Canadian channel lineup — a single Plex or Channels DVR setup gives you live OTA and streaming services side-by-side in the same interface.

What you need

• MyGica A681 USB ATSC tuner — $39.99 CAD, ships with a small starter antenna.
• A host computer, NAS, or media server with a free USB-A port. Most modern Windows / macOS / Linux machines work; the A681 is the size of a USB stick and draws minimal power.
• An antenna — indoor or outdoor depending on your distance from the nearest transmitter (see Step 2 below).
• DVR software — Plex DVR (requires Plex Pass), Channels DVR (annual subscription), NextPVR (free, Windows), or MyGica's bundled app for basic live viewing.
• Optional: a coax extension if your antenna's run is long, and a signal amplifier if you're at the edge of a transmitter's range.

Step-by-step setup

Step 1 — Find out what's actually broadcasting near you

Before you buy anything, check what stations you can realistically receive. The two best tools:

• RabbitEars.info — punch in your postal code, get a transmitter list with distances and compass bearings.
• CRTC Broadcasting Procedure 2020-1 for official Canadian transmitter records.

Major Canadian transmitter clusters worth knowing:

• Toronto: CN Tower cluster — the strongest urban signal in Canada.
• Montreal: Mount Royal.
• Vancouver: Mt Seymour and Burnaby Mountain.
• Ottawa: Camp Fortune and Camp Robinson.
• Calgary: Old Banff Coach Road.
• Edmonton: Beverly Hill transmitter.
• Halifax: Geizer's Hill.

Write down the transmitter distance (km) and bearing (degrees from true north). You'll need both to pick the right antenna.

Step 2 — Pick the right antenna

Antenna selection is the single biggest factor in how many channels you'll receive. Pick by distance to the nearest transmitter:

• Under 25 km: An indoor flat panel antenna in the $25–40 range is almost always enough. Mount it in a window facing the transmitter for best results.
• 25–60 km: Amplified indoor antenna or attic-mount unit. The amplifier matters — look for a 25 dB gain unit with an LTE filter.
• 60–100 km: Outdoor directional Yagi antenna, mounted on the roof or in the attic, pointed at the transmitter bearing.
• Over 100 km or rural: Large outdoor Yagi with a low-noise amplifier (LNA) at the antenna head, not at the tuner end. You'll be in fringe territory — results vary by terrain.

If you're undecided, start cheap. A $35 indoor antenna will tell you within ten minutes whether your location is workable. If it pulls in nothing, upgrade. If it pulls in CBC, CTV, and Global cleanly, you're done.

Step 3 — Plug in the MyGica A681

Connect the antenna's coax cable to the A681's F-connector, finger-tight, then a quarter turn with pliers. Plug the A681 into a USB port on the host computer.

Driver behaviour:

• Windows 10/11: The A681 is plug-and-play. Drivers install automatically. If Device Manager shows a yellow exclamation, install drivers from MyGica's website manually.
• macOS: Use the bundled or open-source ATSC driver. Channels DVR ships with native support.
• Linux: Most modern kernels include the DVB-ATSC module. Check dmesg after plugging in to confirm the tuner is detected.

Step 4 — Install your DVR software

You have four good options:

• Plex DVR (requires Plex Pass, $5/month or $120 lifetime) — the best UI of the bunch, integrates cleanly with an existing Plex library, plays back through any Plex client (including the Plex apps on Formuler and Dreamlink streaming boxes).
• Channels DVR ($8/month or $80/year) — the best EPG and best live-viewing experience. Worth the premium if OTA is your primary content source.
• NextPVR (free, Windows) — no UI awards but fully functional, scriptable, and the price is right.
• MyGica's bundled app — basic but works for live viewing on the host computer. No DVR scheduling.

For most households the right pick is Plex DVR if you already run Plex, Channels DVR if you don't.

Step 5 — Run a channel scan

Important rule: always run the channel scan with the antenna in its final mounting position. Moving the antenna after the scan invalidates the results.

Expect 15–35 channels in major Canadian markets, 5–15 in mid-size cities, fewer in rural areas. Save the scan and label channels by network name (CBC Toronto, CTV Two Ottawa, etc.) so the EPG looks clean.

Step 6 — Pair with your streaming box

This is where the magic happens. With Plex or Channels DVR running on the host computer, install the corresponding app on your Formuler Z12 Ultra, Z11 Pro Max, or Dreamlink Dlite+ 5G. The streaming box becomes the front-end for OTA live TV, recordings, and your streaming services — all in one interface.

Turn on HDMI-CEC on the TV and the streaming box so a single remote (the Formuler BT3, ideally) handles everything.

Antenna placement tips that actually work

Three things drive over-the-air reception more than antenna brand:

• Higher is better. Attic beats living room beats basement, every time. Get the antenna above the roofline if you can.
• Avoid obstructions between antenna and transmitter. Metal roofs, foil-backed insulation, brick exterior walls, and large trees all degrade reception. A south-facing window can outperform an attic mount that's blocked by a chimney.
• Rotate before you upgrade. 180 degrees of antenna rotation can mean the difference between 8 and 28 channels. Try every orientation before deciding the antenna isn't strong enough.

Troubleshooting

"No channels found"

• Re-check the coax connection at both ends — finger-tight, then a quarter turn with pliers. A loose F-connector kills signal.
• Confirm your antenna type matches the broadcast band. Most Canadian transmitters use UHF, but some VHF stations still exist. A UHF-only antenna will miss VHF channels.
• Move the antenna 3–4 feet and rescan. Multipath interference — signal bouncing off buildings — is real and very location-dependent.

"Channels drop out or pixelate"

• Signal is too weak. Add a 25 dB preamp at the antenna head (not at the tuner end), or upgrade to a higher-gain antenna.
• Check for nearby LTE or 5G cell-tower interference. An LTE filter ($15) inline between the antenna and the tuner solves most of these.
• Coax run too long? Keep it under 50 feet, or upgrade to RG6 quad-shield cable for longer runs.

"Tuner not detected"

• Try a different USB port — ideally directly on the motherboard, not behind a hub.
• Windows: update drivers from MyGica's website manually if auto-install didn't work.
• Linux: check dmesg for device enumeration. If the kernel doesn't see the tuner, you may need the em28xx or related DVB module loaded.
• Power-hungry USB hubs help if your host port is undervolted.

"Audio is out of sync on recordings"

• In Plex DVR: switch transcoding from "Make my CPU hurt" to "Direct Stream" for OTA channels. The A681's MPEG-2 output transcodes cleanly without re-encoding.
• Underpowered host CPU? Offload transcoding to a dedicated streaming box like the Z12 Ultra — it has plenty of headroom for live OTA decoding.

The full Canadian streaming household stack

Here's the configuration we recommend for households who want a complete TV setup without a monthly bill:

• MyGica A681 ATSC tuner ($40) + indoor antenna ($35) — free Canadian over-the-air channels.
• Formuler Z11 Pro Max ($190) or Dreamlink Dlite+ 5G ($120) — main streaming box for apps, services, and Plex playback.
• Plex Pass or Channels DVR ($80–$120/year) — the glue that ties live OTA and on-demand into one interface.
• Optional: a paid streaming service or portal of your choice for specialty content not available over the air.

Up-front hardware total: roughly $345–$415 CAD, one-time. After that, the ongoing cost is just whatever streaming services you choose to keep — the OTA channels stay free forever.

The bottom line

A $40 MyGica A681 plus a $35 antenna replaces roughly $25–$30 of basic broadcast channels per month from any paid service — payback in three months, then it's pure savings for the next decade. Pair it with a Formuler or Dreamlink streaming box and you've built a better TV setup than 90% of Canadian households for under $500 total.

The A681 ships free across Canada and the USA from our Ottawa warehouse — no customs paperwork, no duties, 2-year manufacturer warranty, 30-day returns.
