Best TV antenna for Sioux City, IA
Sioux City TV market · 6 stations · tower locations from FCC records, checked October 30, 2026
The short answer
- Get an antenna rated for VHF-high (channels 7–13) and UHF; many flat "HD" antennas are weak on VHF-high.
- Most towers are 11 miles northeast of Sioux City; aim northeast. Exceptions: KXNE-TV (48 miles west-southwest).
- From most of Sioux City an indoor antenna by a window often works; go to the attic or roof if you're in a basement, behind a hill or want the VHF stations.
- Nothing special is needed for NextGen TV (ATSC 3.0): the same antenna works.

Where Sioux City’s TV towers are
The channel number on your TV isn’t the frequency the station uses. The “real channel” decides which antenna you need: 2–6 is VHF-low, 7–13 VHF-high, 14–36 UHF.
| Station | Real channel | Tower from Sioux City |
|---|---|---|
| KSIN-TV (PBS 27) | 28 · UHF | 5 miles east-northeast |
| KCAU-TV (ABC 9) | 9 · VHF-high | 10 miles northeast |
| KTIV (NBC 4) NBC, CW | 14 · UHF | 11 miles northeast |
| KMEG (ROAR 14) | 32 · UHF | 11 miles northeast |
| KPTH (FOX 44) FOX, CBS | 30 · UHF | 11 miles northeast |
| KXNE-TV (PBS 19) | 19 · UHF | 48 miles west-southwest |
The VHF stations to plan for
KCAU-TV (ABC 9) broadcasts on VHF-high (real channel 9). If those drop out while UHF stations come in fine, the antenna is the likely cause: pick one that lists VHF-high reception, or extend the rabbit-ear dipoles on an indoor model.
Which type to buy
- Indoor antenna: fine if you’re within roughly 20 miles of the towers with a window facing them, and if it lists VHF reception. Put it high and near the window.
- Attic or outdoor antenna: the better choice beyond about 20–25 miles, behind hills, or for the VHF stations. Outdoors beats attic; roofing and insulation absorb signal.
- Preamplifier: helps with long cable runs, several TVs on one antenna, or fringe distances. It can make things worse if you’re very close to the towers, because strong signals overload it.
- Skip anything sold as a special “4K”, “HD” or “NextGen TV” antenna. Antennas don’t have formats; only the bands and the gain matter.
Questions
What kind of antenna do I need in Sioux City?
You need an antenna rated for VHF-high (channels 7–13) and UHF; many flat "HD" antennas are weak on VHF-high. From most of Sioux City an indoor antenna by a window often works; go to the attic or roof if you're in a basement, behind a hill or want the VHF stations.
Which way should I point my antenna in Sioux City?
Most towers are 11 miles northeast of Sioux City; aim northeast. Exceptions: KXNE-TV (48 miles west-southwest).
Why can't my antenna get KCAU-TV (ABC 9)?
KCAU-TV (ABC 9) broadcast on VHF (real channel 9), even though your TV shows a different channel number. Many flat and "HD" indoor antennas are designed mainly for UHF and pick up VHF poorly. An antenna with longer VHF elements, mounted higher, usually fixes it.
Do I need a new antenna for NextGen TV (ATSC 3.0) in Sioux City?
No. NextGen TV uses the same channels, so any antenna that gets your stations today will get their NextGen TV versions. What you need is a TV or converter box with a 3.0 tuner.
