Factors To Consider Before Getting Yourself the RF Modulator

Best RF Modulator

When buying essential tech accessories like RF modulators, there are some underlying factors to consider. If you go through this way, you can easily reach a certain point of buying.

Thus, we have designed this buying guide with the crucial factors of the RF modulators. And it will certainly help you to choose the best HDMI rf modulator.


Generally, there are two types of RF modulators in terms of connectivity one is RCA based, and the other is both RCA and HDMI based. If your device only has the RCA-based connector, then you need not buy the RCA and HDMI-based modulator.

However, if you intend to use multiple devices which need both ports, then you must choose both port-based modulators. For example, devices like laptops, desktop computers, and some latest gaming consoles support only HDMI ports.

On the other hand, if your devices are limited to VCRs, DVR players, old gaming consoles, and other media players, then you can go with the classic RF modulator that has only the RCA port.

Therefore, you must ensure the port supports before confirming the RF modulators.

Essential Accessories

When examining these rf modulators, we have noticed that not all the modulators come with every essential accessory. Isn’t it troublesome if you need to buy the accessories separately?

To operate a modulator, you must need these accessories such as a power adapter, RCA cables, remotes, wall mount, and HDMI cables if needed. However, all of the RF modulators come with basic accessories such as adapters and RCA cables.

On the other hand, if you want to connect an HDMI-based device to your RCA modulator, then you need to buy an HDMI to RCA converter. Plus, an HDMI cable is also required for such a connection.


Sometimes, buying an RF modulator is confusing when you intend to use multiple devices. Because a particular device demands a particular modulator. In this case, you must examine the right compatibility of the devices.

All of the classic modulators are compatible with DVR players, VCRs, classic game consoles, and other media players. Most of the time, these devices are easily compatible with the classic modulator.

HDMI-based devices need a particular modulator. So, you must check twice the compatibility of the modulator.

Set Up Friendliness

Unlike classical rf modulator that comes with very basic function, other modulators have multiple functions, especially those that have both RCA and HDMI support. However, if the modulators don’t come with a friendly installation and connection set, then it would be a really troublesome matter for most users.

However, to make your setup easy, we have provided the most common set of instructions for the RF modulators.

How to Connect RF Modulator to Old TV

How to Connect RF Modulator to Old TV

Rf modulator setup wouldn’t be an issue if you put the right jack to the right plug. Thus, you must follow the manufacturer to get the proper connection at the first attempt. Here we discussed those guidelines step by step:

Step 1: Take the coaxial cables which come with the modulator and connect it to the “RF IN” plug of the tv. Some TV has an “ANT IN” plug that is synonymous with the “RF IN” plug. You must push the coax jack a little forward to the endpoint of the “ANT IN” plug.

Step 2: Now input the same coaxial cable to the “RF IN” plug of the modulator. You must ensure the proper input.

Step 3: Take the AV cable set, and plug in the individual jack according to the AV color code to the DVD, VCR, media player, or game console. More specifically, yellow for video, red for right audio, and white for stereo audio.

Step 4: Connect the other parts of that AV cable to the RF modulator according to the color code. Now, input the power adapter and turn on each device.

Note: If the tv whenever connected to the RF modulator, it automatically switches to the modulator function when turned on the modulator.
