When browsing, make sure to check if the product you want to purchase offers extra peripherals included, such as cables, connectors, power adapters, etc.

These peripherals will save you some money and time during the installation process, and since you will be paying a decent sum for this product, you should ensure to get the most out of the price you are paying.

4. Why do I need HDMI RF modulator?

You require this modulator for transforming the HDMI input signal to a radio frequency (RF antenna) signal. This is a useful method for eliminating the use of dedicated cabling, so it is also very convenient.

5. Does the RF modulator boost the signal?

Modulating signal refers to the integration of a signal with another wave of a higher frequency. This reduces the attenuation throughout the transmission of waves over long distances, and it does increase the range.
