When I was trying out a bunch of live TV streaming services, I eventually landed on an indoor antenna I picked up from Best Buy for cheap thanks to a bunch of gift certificates. I used it for a little while before realizing I had practically no use for it. Any channel that it picked up would be available on a live TV service where I could use a DVR and get better quality without having an eyesore on my wall.
I don’t have anything against people who use indoor antennas, and I passed this one on to my dad, who also used it for a little while before taking it down. As it turns out, I actually do need one of these if I want to watch my local sports teams. Living in Detroit, I haven’t had access to any of my local sports broadcasts since YouTube TV, Hulu + Live TV, and every other live stream dropped the networks years ago.
I could sign up for the FanDuel Sports Network and pay $20 a month, but that never appealed to me. Now that that company is on the way out, the Pistons are going to local TV. I was happy to hear that, but that happiness waned when I realized I still didn’t have access to myTV20, the channel that will broadcast the games. Yep, you guessed it, I need an antenna.
Digital TV antennas
Trivia challenge
From signal strength to antenna types — find out how much you really know
about cutting the cord.
SignalsHardwareTechnologyInstallationStandards
What frequency bands do most digital TV antennas in the US receive over-the-air
broadcasts on?
Correct! Digital TV broadcasts in the US use VHF (Very High Frequency,
channels 2–13) and UHF (Ultra High Frequency, channels 14–36). After the 2009 digital transition, most
stations shifted to UHF, though some VHF channels remain active.
Not quite. Digital TV antennas receive VHF and UHF signals. AM and FM
are radio bands, while C-band and Ku-band are used for satellite communications, not over-the-air TV.
What does the term ‘ATSC’ stand for in the context of US digital TV broadcasting?
Correct! ATSC stands for Advanced Television Systems Committee, the
organization that developed the digital broadcast standards used in the US, Canada, and Mexico. ATSC
replaced the older analog NTSC standard when the US transitioned to digital TV in 2009.
Not quite. ATSC stands for Advanced Television Systems Committee. It’s
the body responsible for developing the digital broadcast standard that replaced analog NTSC television
in the United States in 2009.
What is the primary advantage of an amplified digital TV antenna over a passive one?
Correct! An amplified antenna includes a built-in signal booster that
strengthens weak signals, making it useful for viewers who are far from broadcast towers or in areas
with interference. However, over-amplification can actually degrade signal quality if you’re close to
towers.
Not quite. Amplified antennas boost weak incoming signals using a
built-in amplifier, helping viewers at greater distances from broadcast towers get cleaner reception.
They don’t receive satellite signals or rotate automatically.
Which next-generation US broadcast standard promises 4K HDR over-the-air TV and is
gradually being rolled out?
Correct! ATSC 3.0, also marketed as ‘NextGen TV,’ supports 4K Ultra HD,
HDR, Dolby Atmos audio, and interactive features. It’s an IP-based standard that’s being voluntarily
rolled out across major US markets, though it requires a new tuner to receive.
Not quite. The answer is ATSC 3.0, branded as NextGen TV. DVB-T2 is the
European digital broadcast standard, and ISDB-T is used in Japan and parts of South America. ATSC 2.0
was proposed but never deployed commercially.
Why is it generally recommended to mount an outdoor TV antenna as high as possible?
Correct! TV signals travel in roughly straight lines, so mounting an
antenna higher gives it a better line-of-sight path to distant broadcast towers. Trees, buildings, and
terrain can block or reflect signals, and elevation helps minimize these obstructions.
Not quite. The main reason is line-of-sight — higher placement reduces
physical obstructions like trees and buildings between the antenna and broadcast towers. Signal altitude
and air temperature have no meaningful impact on reception.
What is ‘multipath interference’ in the context of digital TV antenna reception?
Correct! Multipath interference occurs when a broadcast signal reflects
off buildings, hills, or other surfaces and arrives at the antenna at slightly different times. These
overlapping copies of the same signal can confuse the tuner, causing pixelation or signal dropouts.
Not quite. Multipath interference is when reflected copies of the same
signal arrive at the antenna at different times, causing the tuner to receive conflicting data. It’s a
common issue in urban areas with lots of large reflective surfaces like buildings.
What does a coaxial cable splitter do when used with a TV antenna, and what is its
main drawback?
Correct! A coaxial splitter divides one antenna signal among multiple
televisions, but each split reduces signal strength — a two-way splitter typically cuts signal by around
3.5 dB per output. In weak-signal areas, this loss can cause reception problems without a distribution
amplifier to compensate.
Not quite. A splitter distributes the antenna’s signal to multiple TVs,
but it weakens the signal at each output in the process. A passive splitter doesn’t amplify or filter —
it simply divides, which is why signal loss is its biggest downside.
Which free online tool, run by the FCC, is most commonly recommended for finding
broadcast towers and choosing the right antenna for your location?
Correct! The FCC’s DTV Reception Maps tool at dtv.gov allows users to
enter their address and see which over-the-air channels are available, the direction of nearby towers,
and expected signal strength. It’s the official resource for planning antenna placement and selection.
Not quite. While TV Fool and RabbitEars.info are popular community
tools, the official FCC-run resource is the DTV Reception Maps available at dtv.gov. It uses the FCC’s
own broadcast data to show coverage and signal strength at your specific address.

The antenna comes calling again
This shouldn’t be a thing
I tried the antenna life already and decided it wasn’t for me, so I really don’t want to go back to it if I don’t have to. Unfortunately, I don’t know if there’s going to be a way around that unless every local channel I don’t get offers an app of some sort. Antennas aren’t too expensive, and since I live in the city, picking up a station’s signal is no problem at all. However, I’d just like to subscribe to a live TV service that has all the channels I want in the first place. Strangely, an actual cable network is my best solution to that, but there’s no way I’m bringing boxes back into my house.
My only option now is to hold out hope that the Pistons can find a way onto YouTube TV, or I can just pick up an antenna again. The good news is that this is the only thing I’d use the antenna for, so it’s not like I’d need to lament the loss of a DVR or struggle with flipping through channels, because I only want one. Then again, it feels weird that I have to go out and slap an ugly square on my wall just to get a single channel, but I don’t see a better solution as somebody who wants to save as much money as possible.
Live TV services should just offer me the channels that I want, but in this world where every penny has to be squeezed out of you, I don’t think it’s going to happen. I don’t want to sound like I hate indoor antennas, because that’s far from the case. If I were really looking to cut costs, an antenna could certainly work. I can get quite a few channels from one, but that’s largely because I live in a city. If you live in a rural area, you won’t have the same luck unless you buy one with a long range, and even then it’s hit or miss.
It’s these sports networks that are really the bane of my existence, and I swear it’s one of the things keeping cable afloat. The rights for sports are so spread out now that you need access to a variety of channels and streaming services to keep up with everything. I simply don’t have the desire to do that, but I would like to watch my local teams on a free channel if I can. I guess it is time to get that antenna back out.
Don’t count on the antenna to solve all your problems
They have limitations
You might think that you can simply cut the cord and go to an antenna, but it’s not as simple as that. An antenna gives you access to the channels, but you’ll find a bunch of them are channels you’d never want to watch in the first place. You can figure out what these channels are beforehand using a site like RabbitEars.Info. If you see a bunch of stations you don’t have any interest in, then you can save yourself the trouble of setting up an antenna.
I find that antennas gain the most value when you’re trying to pick up local stations. You can pair an antenna with a streaming service like Netflix or HBO Max and cover a lot of bases that way. Everyone’s trying to keep costs down, and an indoor antenna is just a one-time buy that does just that. You can also get a DVR for your antenna if you’d like, but it’ll cost you a little extra.
