Omnidirectional or directional, on a vehicle
Omnidirectional: the default for travel
You arrive somewhere new, the transmitters are on a bearing you have not looked up, and the coach is parked however the site allows. An omnidirectional antenna — the Omni+ 50 publishes a 50-mile manufacturer claim and a 360-degree pattern — handles that without you climbing anything. It also keeps working when you move the rig six feet to level it.
Directional: for a site you stay on
If the RV lives on one site for a season, or you return to the same couple of parks every year, a directional antenna aimed once is a real upgrade: more gain in the direction that matters, and better rejection of noise from everywhere else. The ClearStream 2MAX mounts on a mast or a wall bracket and is the pick for that, and the STEALTHtenna Elite 60 is the one-box version that arrives with its mount, cable and amplifier so you are not specifying parts.
What a mile claim is worth
Range figures on antenna boxes are the manufacturer’s own marketing claims with no standard test behind them, and we quote them as such everywhere on this site. On an RV they are even less predictive than usual, because your result depends on where you happen to be parked — in a valley, under trees, behind a hill, or in a park with a clear line of sight to a tower thirty miles away.
The installation realities nobody mentions
The roof is a ground plane, and a liability
A metal RV roof helps a roof-mounted antenna work, and it is also something you should be reluctant to drill. Any new penetration needs the correct sealant for your roof material and inspecting every season; water in an RV roof is far more expensive than any antenna. Three ways to avoid a new hole: reuse the existing antenna’s mount and coax, use a ladder or rear-bumper pole mount, or use a magnetic or clamp mount where the antenna’s hardware allows. Mounting on a vehicle is an install job on our Setup scale for exactly this reason, and if you are not comfortable on a roof, this is work to hire.
Height, clearance and travel
Anything you add to the roof becomes part of your clearance height. Measure, write the new number where you will see it before a low bridge, and check that the antenna can survive highway speed and wind loading in the position you have chosen. Some directional antennas are designed to be lowered for travel; a fixed one must be mounted to take the abuse.
Amplifiers need power you may not have
An amplified antenna needs power at the amplifier. The STEALTHtenna kit powers its amplifier from mains at the indoor end, which means a shore power hookup or an inverter — fine on a serviced site, not fine on a dry camp running down a battery. The Omni+ 50 and the ClearStream 2MAX are passive, so they need nothing at all. On a vehicle, passive is one less thing to go wrong.
Two televisions means a distribution amplifier
Splitting one antenna feed between a lounge television and a bedroom television costs signal at both. That is the one job a distribution amplifier genuinely does: the Channel Master 4-port unit publishes 7.5dB of gain and a built-in LTE filter, which is useful at a park full of cellular equipment and other rigs. It fixes splitter and cable loss. It does not fix a weak signal from a distant tower, and our amplifier page is blunt about that line.
Getting channels at a new site
Look the site up before you arrive.The FCC’s address-level reception map takes a street address and returns the stations predicted there, their strength and the direction of each transmitter. Enter the park’s address and you will know before you tow whether television is realistic or whether the valley you are heading into gets nothing.
Rescan every single time you move. Your television only knows about the channels it found during its last scan, and at a new site those channels are different. This is the step people skip before deciding the antenna is faulty.
Park with the antenna in mind if you can. With a directional antenna that means pointing the coach so the antenna faces the towers. With any antenna it means avoiding parking the rig so a neighboring motorhome, a building or a dense stand of trees sits between you and the transmitters.
Scan with the amplifier off as well as on. If your setup has a switchable amplifier, try both. Amplification raises signal and noise together, so at a site close to a transmitter it can overload the tuner and find fewer channels than the passive scan does.
What this gets you, and what it does not
It gets you local channels free, with no internet involved and no subscription — which is the best feature any RV entertainment setup has, because campground Wi-Fi and cellular data are both unreliable and sometimes absent. Local news, weather and the major networks are exactly what you want when you are traveling, and the weather coverage alone justifies the antenna.
It does not get you cable channels, and it does not get you streaming. For those you need a connection, which is a separate problem with separate answers: our RV Wi-Fi page covers making a weak campground connection usable, and the camping cell booster page covers the case where there is no Wi-Fi at all. It also will not work while you are moving — broadcast reception at highway speed is not what any of this hardware is for.
And if the coach television has no coax socket labeled ANT IN or ANT/CABLE, it has no tuner, and an antenna alone cannot help. In that case a network tuner or over-the-air DVR puts broadcast channels onto the coach network and into an app instead.
