For homeowners

Know when weak signals may be temporary.
Avoid rescanning during bad signal windows.
Understand when strong conditions should make your channels behave.
Spot the difference between a weather day and an antenna system that needs service.

For cord cutters

Check West Michigan antenna conditions before judging your setup.
See when conditions are good enough that persistent issues may point to equipment, aiming, coax, filters, or amplification.
Use the index before calling for repair, upgrade, or a proper installation.
Know when your TV is confused because the atmosphere decided to play landlord.

Still having trouble?

Good signal conditions and bad TV reception usually means the problem is in the system.

Transition TV can check antenna aim, coax, splitters, filters, amplifiers, mounting, and weather damage before the remote gets blamed for crimes it did not commit.

Frequently Asked Questions

What is the Signal Index?

The West Michigan TV Signal Index is a live reception forecast that estimates how favorable current conditions are for over-the-air TV reception. It combines weather, season, wind, sky conditions, time of day, regional trends, and other factors into a simple 0–100 score.

What does the score mean?

The score represents when your weakest, most distant TV stations are most likely to begin breaking up or disappearing, assuming your antenna system is properly installed and optimized.
A higher score means current conditions are favorable for TV reception. Fringe channels should perform closer to their normal potential, making it a good time to troubleshoot or rescan if needed.
A lower score means today’s weather and atmospheric conditions are making reception more difficult. Fringe channels are usually affected first, even on well-installed antenna systems.

How does this help me?

The Signal Index helps determine whether today’s reception problems are likely caused by changing weather conditions or by your antenna system. If the Index is high but reception is poor, the issue is usually your equipment rather than the weather. You may need to schedule service if your system is acting up.

Should I rescan my TV today?

Usually only during Good or Excellent conditions. Contrary to online advice and intuition, rescanning during weak conditions will not bring your channels back; it will cause you to lose them off your TVs channel list. Rescanning during Poor or Weak conditions can cause your TV to remove channels that return once conditions improve; but you won’t see them again unless you rescan during normal conditions.

Why are only some channels missing?

Weaker and more distant stations are affected first as conditions worsen. Strong local stations often continue working while fringe channels begin breaking up or disappear.

Does this predict every channel?

No. The Signal Index reflects overall reception conditions across West Michigan. Strong local stations may continue working even during lower Index values, while weaker fringe stations are more sensitive to changing conditions. For full channel lineups, use our Channel Search under Channels.

Does weather affect antenna TV?

Yes. Wind, humidity, storms, atmospheric pressure, seasonal foliage, sky conditions, and other environmental factors all influence over-the-air television reception. Contrary to how satellite service can break up on cloudy days, the opposite is true for TV antenna. Because OTA signals are under the clouds, it’s clear skies that can make them weaker, and cloudy skies than can extend them further.

Why does the season matter?

Winter generally offers the best reception because of drier air and fewer leaves. Summer often produces the weakest conditions due to dense foliage, higher humidity, haze, and increased atmospheric instability.

What is tropospheric ducting?

Tropospheric ducting temporarily allows TV signals to travel much farther than normal. While it can improve reception of distant stations, it can also create interference with local channels, overlapping shared frequencies from two different areas. A channel scan during these temporary 2 to 5 hour events, can yield up to twice as many channels as normsl. However, the tropospheric signals soon fade away, leaving only your local area stations tuned in. The Signal Index recognizes these temporary conditions and accounts for them to help you understand when your TV is lying to you and producing excellent, but false-temporary results.

What if my reception is poor during a high score?

That’s usually a sign your antenna system needs attention. Antenna aim, damaged coax, splitters, amplifiers, mounting hardware, faulty grounding, or connectors are more likely to be the cause than today’s weather. Schedule service if you are experiencing trouble during high Signal Index times.

What if my score stays low?

Poor or Weak conditions are often temporary. Check the Signal History to see whether conditions are improving, or schedule a SignalCare, Repair, Upgrade, or Installation evaluation if reception problems continue during Good or Excellent conditions.

How often is the Index updated?

The Signal Index automatically refreshes hourly throughout the day using live weather observations and forecast data. Historical readings are also stored so you can compare conditions over time.

Who is the Signal Index for?

Anyone using a TV antenna in West Michigan, from viewers receiving only local stations to hobbyists pulling in distant fringe channels.

Why is the Signal Index unique?

Unlike weather forecasts, the Signal Index translates live weather and atmospheric data into a practical forecast for antenna TV reception. Because assumptions about how weather affects reception is often wrong, the Signal Index clears up the myths and misleading online information. It helps explain when today’s conditions are limiting your reception and when your antenna system deserves a closer look. It was designed by Jeramie, to help area OTA viewers know if it’s weather causing the problem, or their antenna. No other company offers this…anywhere.

Is this only for West Michigan?

Yes. The Signal Index is specifically designed and calibrated for over-the-air television reception across West Michigan. This includes areas from Ludington to Benton Harbor, Big Rapids to Battle Creek, and every place inbetween.

Is the Signal Index free?

Yes. Anyone can use the Signal Index to check current antenna reception conditions across West Michigan, and determine whether today’s signal issues are likely weather-related.
