Comparison and Buying Insights

Choosing the right device comes down to defining your goal. Is it to connect a modern device to an old TV, or is it to send a modern signal over a long distance using existing coax?

If you need to connect HDMI to an Analog TV (RF Modulator):
Focus on Products 1 and 3. Both are HDM61 modulators and handle the specific conversion from digital HDMI to analog NTSC CH3/CH4 RF signal. These are the only options for TVs that only have a single coaxial screw-in antenna input and no separate RCA or HDMI ports. Remember, while the input supports 1080P, the output will be standard definition analog video.

If you need to connect a CCTV System (BNC Converter):
Focus on Products 2 and 5. These devices convert BNC (CVBS analog) signals from security cameras or DVRs into HDMI. They are specifically not for cable TV or standard RF connections. Product 5 offers superior 3D compensation technology if image clarity is your primary concern.

If you need Long Distance Extension (Digital Extender):
Product 4 (OREI) is the sole option here. This device keeps the signal digital and high resolution, using coax purely as a high-speed conduit. It’s essential for 4K extension up to 330 feet and is far different from the analog conversion devices.

Critical Note on Coaxial Types:
When searching for the best hdmi to coax cable best buy, always check the connector. Most standard TVs and cable boxes use the F-type screw connector. BNC converters use the BNC connector (common in surveillance). The RF modulators (P1, P3) output F-type, while the BNC converters (P2, P5) input BNC.

Final Verdict: Choosing Your Converter Type

Finding the best hdmi to coax cable best buy isn’t about one “best” product, but the right tool for the job.

For maximum compatibility with vintage US televisions, the HDMI to RF Modulator, VHF RF Modulator HDMI Coaxial Converter (P1/P3) is your necessary hardware. It bridges the gap between digital HDMI and analog RF antenna inputs effectively.

Frequently Asked Questions About Best HDMI to Coax Cable Best Buy

What is the difference between an RF Modulator and a BNC Converter?

An RF Modulator (like P1 or P3) converts a digital HDMI signal into an analog radio frequency signal (VHF CH3/CH4). This is used to connect new devices to old televisions that only have an antenna input. A BNC Converter (like P2 or P5) takes an analog CVBS BNC video signal, typically from a security camera or DVR, and converts it into a digital HDMI signal for viewing on a modern monitor. They serve completely different purposes.

Can I run a 4K HDMI signal over a coaxial cable using an RF modulator?

No. RF modulators (P1 and P3) convert the digital signal into an analog signal limited to standard definition (SD) quality (NTSC format). If you need to transmit true digital 4K over coaxial cable, you must use a dedicated HDMI Over Coax Extender (like P4), which keeps the signal digital the entire way.

Do I need a power supply for these HDMI to Coax converters?

Yes, almost all high-quality HDMI to coax or BNC converters, especially those that include upscaling or modulation chips, require an external power supply (usually a 5V adapter). The conversion process needs stable power to correctly process the signal change.

How do I know if my old TV requires an RF Modulator?

If your television only has a single screw-in input labeled “Antenna” or “RF In” and lacks the colored red, white, and yellow RCA inputs or modern HDMI ports, you will need an RF modulator to view content from new HDMI devices.

Can these adapters convert RF cable TV signals back into HDMI?

No, the products listed here (P1, P3, P4) are strictly for converting or extending HDMI to coax/RF. They are one-way devices. To watch cable TV on a monitor that only accepts HDMI, you would need a completely different device known as an RF to HDMI Converter, which is not covered in this guide to finding the best hdmi to coax cable best buy.

What is CVBS and why is it important for BNC converters?

CVBS stands for Composite Video Blanking and Sync, and it is the standard analog video signal used by older security cameras (CCTV). BNC converters (P2 and P5) are designed to specifically handle the analog signal protocol from these CVBS cameras. They are not compatible with newer digital surveillance standards like AHD, TVI, or CVI.
