The blocked channels of a radio jammer for sale can vary depending on the design and configuration of the device. Different types of radio jammers may have different frequency ranges and capabilities. Here are some common radio channels or bands that may be blocked by radio jammers:
AM Broadcast Channels: AM (amplitude modulation) broadcast channels are usually in the frequency range between Medium Wave and Shortwave. Radio jammers may cover these frequency ranges, causing interference to AM broadcast reception.
FM Radio Channel: FM (Frequency Modulation) radio channel is usually in the frequency range between Frequency Modulation Radio (FM) and VHF (Very High Frequency). Radio jammers may interfere with these frequency ranges, causing interference to FM broadcast reception.
Mobile communication frequency bands: Radio jammers may also affect mobile communication frequency bands, including cellular networks (such as GSM, 3G, 4G, 5G), wireless LAN (Wi-Fi) and Bluetooth, etc. These bands are typically in the higher frequency ranges such as 800 MHz, 1.8 GHz, 2.4 GHz and 5 GHz.
It is important to note that modern radio communication systems often use multiple frequency bands and channels, covering a wide frequency range. Therefore, it is very difficult for a radio jammer to completely block all channels. Additionally, radio jammers may vary in design and functionality and may only target specific frequency bands or channels.
Please note that the unauthorized use of signal blcokers is illegal and may interfere with the normal communications of others.
