Modulating a clean channel onto coaxial cable is harder than it looks: weak modulators fade across splitters, distort on long runs, or interfere with the channels already on the line. The MINIMOD 2+ earned NAB Product of the Year, CE Pro Best, and CEDIA Best of Show because it drives the coax at broadcast quality β +45 dBmV output and MER above 45 dB β so the channel stays perfect from the headend to the farthest television on the cable.
Recognition
The Coax Modulator Integrators Have Trusted Since 2017
When the job is to put a source on the coaxial cable and feed every TV in a building, the VeCOAX MINIMOD 2+ is the coax modulator professionals reach for β award-winning, US-built, proven on 50,000+ installations.
How a Coax Modulator Works
HDMI In β A Real Channel on Your Coaxial Cable
A coax modulator reuses the coaxial cable already in your walls: it turns an HDMI source into a channel that rides the existing coax to every outlet β no new wiring, no network.
- Connect any HDMI source β cable box, player, camera, or laptop
- Pick a channel on the LCD; the HDMI now travels on your coax
- Land the coax output on the existing trunk or a splitter β reuse what's there
- Scan each TV once and the channel appears on the in-wall coax in 1080p
- No fresh cable pulls, no Cat6, no decoder behind any television
- Add modulators and combine their outputs onto the same coaxial run
Setup
Put a Channel on the Coax in Under a Minute. No Computer Required.
Most coax modulators want a laptop to configure. This one keeps channel, modulation, and level on a color LCD so you put a source on the coax in under a minute.
- The display shows channel, coax frequency, and lock state continuously
- Choose the modulation and set the channel from the front buttons
- Standalone unit β no software, serial cable, or driver for coax setup
- Power on β pick channel β land coax β scan β live on the cable
Works on Your Existing Line
Your New Channel Rides the Coax Beside Your Current Channels
Run the coax channel as QAM for cable plants or ATSC for antenna plants β it joins the lineup already riding your coaxial cable.
The modulator outputs a compliant broadcast channel on the coax, so the source tunes like a real station. Cable (QAM) sets list it among cable channels; antenna (ATSC) sets add it to the air grid β switch standards on the panel.
DVB-T/C and ISDB-T are supported too, so this coax modulator drops into any coaxial plant worldwide β HD, 4K, or 8K.
Remote Control
Manage Your Coax Modulators From Any Browser
The panel handles install; the optional LAN page lets you retune coax channels and check levels from the bench when modulators sit in a closet.
- Retune the coax channel and trim output level remotely over the LAN
- Manage a rack of coax modulators from one browser screen
- Works in any computer or phone browser β no client to install Built for coax modulator installations.
- Live status confirms each coax channel is on-air and clean
Audio
Audio Travels the Coax Locked to Picture
Sound rides the same coax as the picture. The modulator embeds broadcast Dolby Digital so audio reaches every TV on the cable perfectly synced.
- Dolby Digital / LPCM travels on the coax with the picture
- Audio stays locked to picture across long coax legs β no drift
- Passes 5.1 surround intact from compatible HDMI sources Built for coax modulator installations.
- Clean dialogue, music, and effects on every set on the cable
Installation
Three Connections. Done.
HDMI in. Coax channel out. One scan. The source is live on every coax outlet in Full HD with synced audio.
A coax modulator install is fast: connect the HDMI source, land the F-type output on the existing coax distribution (or a passive combiner), pick a channel on the LCD, and rescan. No new cable, no per-TV decoders, no IT ticket β the coax already in the walls does the work.
The MINIMOD 2+
A Coax Modulator With Broadcast-Headend Quality
Palm-sized aluminum build, broadcast-grade modulation, and a front-panel LCD β the professional way to put a source on coax. Made in USA with a 5-year warranty.

High Density
10+ Coax Channels with the MiniBlade Kit
For large coax lineups, the VeCOAX MiniBlade system packs 10 or more modulator units into a single rack β each fully independent so one channel can never take down the rest.
When you need many channels on the coax at once, the MiniBlade rack kit delivers maximum channel density with independent power per unit. There is no shared point of failure: every channel on the coax runs on its own, which is exactly what 24/7 commercial systems demand.
Compatibility
Every TV on the Coax Tunes the Channel β HD, 4K, and 8K
The coax channel is a standard digital broadcast, so any TV tuner decodes it β from an older HD set to a new 8K display.
Because the coax channel follows broadcast spec, compatibility is automatic. The modulator resolves color, frame rate, and audio sync internally, so the channel renders correctly on every brand and resolution with no per-set setup.

FAQ
Coax Modulator For HDMI - Frequently Asked Questions
What is a coax modulator for HDMI?
A coax modulator for HDMI is a device that turns an HDMI source into a real digital TV channel over coax. For the coax modulator keyword family, the VeCOAX MINIMOD 2+ handles putting HDMI video onto coax as a tunable TV channel and lets every connected TV scan the result like normal television.
How does a coax modulator for HDMI work over coax?
For coax modulator, the MINIMOD 2+ receives HDMI, encodes it as a 1080p digital television channel, and outputs it through the F-type coax connector. The coax network carries that channel to every TV without a box behind each screen.
Why use a coax modulator for HDMI instead of HDMI cables?
Coax Modulator For HDMI distribution uses the coax already installed in the building, so distance and screen count are not limited like HDMI cable runs. This is why coax modulator is better for whole-building TV distribution than point-to-point HDMI wiring.
Which sources work with this coax modulator for HDMI?
Use HDMI media boxes, cameras, receivers, computers, and signage players. For coax modulator installations, the HDMI input includes EDID control so common 720p, 1080i, and 1080p sources can be converted into a stable HD TV channel.
Which TVs can receive the coax modulator channel?
Any TV with a compatible digital tuner can receive the coax modulator channel after a normal scan. HD, 4K, and 8K televisions can tune the 1080p output because it is a standard digital TV broadcast format.
Does this coax modulator for HDMI support QAM cable mode?
Yes. In QAM mode, the MINIMOD 2+ creates a digital cable-TV channel that cable-mode TVs can scan. This is useful for coax modulator in hotels, CATV plants, commercial buildings, and private coax systems.
Does this coax modulator for HDMI support ATSC antenna mode?
Yes. In ATSC mode, the same coax modulator for HDMI creates an antenna-style digital TV channel. This helps coax modulator projects where TVs are set to antenna mode instead of cable/QAM mode.
Can this coax modulator for HDMI coexist with existing TV channels?
Yes. Assign the coax modulator output to an open RF channel so it does not overlap existing cable, antenna, or other private modulator channels. Proper channel planning lets multiple channels share the same coax cleanly.
How many TVs can one coax modulator for HDMI feed?
One MINIMOD 2+ can feed a few TVs or thousands of TVs when the coax system is designed correctly. For coax modulator, the +45 dBmV RF output gives strong launch power for splitters, taps, and long building runs.
How far can coax modulator travel over coax?
Coax Modulator For HDMI output can travel up to roughly 9,800 feet under proper RF conditions. Real distance depends on cable type, splitters, taps, amplifiers, and the signal level required at each TV.
Can I use existing coax with this coax modulator for HDMI?
Yes. This is the main advantage of coax modulator: it reuses RG6 or RG59 coax already in the walls. You do not need to pull new HDMI cables to every display.
Do I need a computer to set up this coax modulator for HDMI?
No. Channel number, modulation standard, output settings, and basic configuration can be set from the built-in color LCD. This makes coax modulator setup fast even without a laptop.
Why is the color LCD important for coax modulator?
The front display lets installers confirm the active channel, standard, and operating status at the rack or TV closet. That makes coaxial TV distribution faster to commission than units that require software for basic setup.
Can I manage this coax modulator for HDMI remotely?
Yes. The MINIMOD 2+ includes secure web browser control for checking status and adjusting settings from a computer, tablet, or phone on the local network, which is useful for coax modulator systems in equipment rooms.
What picture quality does this coax modulator for HDMI deliver?
It delivers Full HD 1080p MPEG-2 video with Dolby Digital audio. Broadcast-grade MER performance and a clean RF synthesizer help the coax modulator channel stay sharp on every TV.
Does this coax modulator for HDMI work with 4K and 8K TVs?
Yes. Modern 4K and 8K TVs can tune and display the 1080p coax modulator channel just like any other HD broadcast channel. For true 4K channel output, use the VeCOAX MINIMOD 4K instead.
Can I add more coax modulator channels later?
Yes. Each MINIMOD 2+ creates one channel. Add more units, set each one to a different RF channel, and combine them onto the same coax for a larger coax modulator lineup.
Where is this coax modulator for HDMI used most often?
This coax modulator for HDMI is used in installations that already have RG6 or RG59 coax in the walls. Typical coax modulator applications include private TV channels, digital signage, camera feeds, welcome channels, training video, live events, and shared entertainment sources.
How is this coax modulator for HDMI different from a long HDMI cable run?
A long HDMI cable run usually depends on short point-to-point wiring or limited outputs. A coax modulator for HDMI creates a real tunable TV channel, so the existing coax system distributes the coax modulator source to every TV at building scale.
Is the MINIMOD 2+ good for professional coax modulator?
Yes. It is designed for 24/7 professional coax modulator with +45 dBmV output, MER above 45 dB, selectable QAM/ATSC/DVB/ISDB standards, web control, and a compact metal chassis.
Is this coax modulator for HDMI HDCP compliant?
The HDMI input is licensed and includes EDID control for compatibility with standard HDMI sources. As with any professional coax modulator system, the connected source content must allow the intended display and distribution use.
What warranty and support come with this coax modulator for HDMI?
The MINIMOD 2+ includes a 5-year manufacturer warranty and free lifetime technical support from Pro Video Instruments. It is designed and made in USA for dependable coaxial TV distribution and strong coax modulator performance.
