A TV in the waiting room, the lobby or the break room is a small thing that customers and staff notice. Many businesses pay a monthly cable or satellite bill to run one, mostly to show local news and weather. Local channels can also come from an antenna, with no monthly bill. Here is what that involves for a business.
What an antenna does and does not get you
An antenna receives free over-the-air broadcasts from local TV stations: the network affiliates, public television and other local channels. It does not receive cable-only channels. It also does not depend on your internet connection or a cable subscription.
For a waiting room that mainly shows local news, weather and daytime programming, that is often all you need. For a sports bar that needs cable sports networks, an antenna can supplement a subscription but not replace it.
Step 1: check the signal at your address
Reception depends on where the building is, how far it is from the broadcast towers and what is in between. The FCC's DTV Reception Maps tool lets you enter an address and see which stations are expected there and roughly how strong their signals are. It is a good first look, but it is a prediction, and the FCC bases it on an outdoor antenna 30 feet above the ground. Metal roofs, concrete walls and nearby buildings all affect what an antenna actually receives, which is why the real test is a signal reading at the spot where the antenna will go.
Step 2: place the antenna
An outdoor antenna, or an attic antenna under a roof that is not metal, usually receives far better than one sitting next to the TV, especially in buildings with metal or concrete construction. On a commercial building, the antenna typically goes on the roof or a wall mount with a clear view toward the towers.
If you lease your space, talk to your landlord first. A roof mount means work on the roof and, usually, a cable entering the building, both of which a landlord will want a say in. An FCC rule limits restrictions on antennas used to receive TV broadcasts, but it applies to property within the antenna user's exclusive use or control. A shared roof in a multi-tenant building is usually not that.
Step 3: ground it properly
An antenna on a roof in Tampa Bay is a lightning question. The National Electrical Code's article on radio and TV equipment (Article 810) generally requires an outdoor antenna mast to be grounded and each lead-in cable to have a listed antenna discharge unit, located as close as practical to where the cable enters the building. It also requires keeping outdoor antennas and their lead-in cables well away from power lines: at least 2 feet from lower-voltage conductors and 10 feet from higher-voltage ones, which matters on commercial buildings. Grounding does not make a building lightning-proof, but it can help reduce damage from nearby strikes and keeps static from building up on the antenna and cable.
Step 4: get the signal to every TV
From the antenna, coaxial cable runs to each TV. One antenna can feed several TVs, but every split weakens the signal each TV receives. A setup for several screens often needs an amplifier: a preamplifier at the antenna to make up for a long cable run, a distribution amplifier ahead of the splits, or both. An amplifier makes up for cable and splitter losses; it cannot rescue a signal that is too weak at the antenna. Planning the cable runs, splits and amplifier together is what keeps the last TV on the line as clear as the first.
If the business already has coax running to its TVs from an old cable or satellite service, some of it may be reusable. It is worth testing before relying on it.
Step 5: scan for channels
Each TV, or each tuner feeding a TV, scans for channels once the antenna is connected. Rescan after any change to the antenna, and occasionally after stations change frequencies.
What NextGen TV means for the TVs you buy
Broadcast TV is in the middle of a change to a new standard, ATSC 3.0, marketed as NextGen TV. In December 2020, five Tampa Bay stations (WMOR, WFTS, WFLA, WTSP and WTVT) announced they were launching NextGen TV broadcasts together, with WMOR hosting the new NextGen TV signals and WFTS, WTSP and WTVT hosting the current-format signals at launch.
The catch, in the FCC's own words, is that "the Next Gen TV standard is not backward-compatible with most existing TV sets or receivers." For now, stations that broadcast in NextGen TV must keep their main programming available in the older format, ATSC 1.0, so most current TVs keep working. In October 2025 the FCC proposed eliminating that simulcasting requirement for stations that switch to ATSC 3.0, and it asked how to weigh that against the cost to viewers who do not yet have 3.0-capable equipment and may lose access to free over-the-air service in the older format.
Nothing changes for the TVs in your lobby today. But if you are buying TVs for the business, a model with an ATSC 3.0 tuner is worth considering, and it is worth watching for news from the FCC before you plan a large purchase.
Is it worth it?
Compare a one-time installation with the monthly bill it replaces, for every TV that only needs local channels. Count the TVs, note where they are and whether any cable already runs to them, and check your address in the FCC tool. Digital TV antennas are one of the low-voltage services we install for businesses across Tampa Bay.
