UHF VHF Jammers for sale

What is the mission of UHF and VHF frequency jammers? You just need to know their frequency range and which electronic devices use these frequencies?You will easily understand the purpose of our UHF and VHF, Radio Signal blocker. The frequency range of VHF and UHF is 140~180MHz and 420~480MHz respectively. These two frequency ranges are often used for CCTV cameras, walkie-talkies, radios and Lojack trackers. If you want to interfere with the above electronic equipment or electronic device using UHF/VHF frequency, our UHF/VHF Blocker will be your best choice.

Radio jamming, or radio frequency jamming, is a common form of jamming that prevents communications between a radio device and other external devices, usually through a device known as a "Radio jammer or RF jammer." These RF blockers transmit a signal on the same frequency (UHF signal or VHF signal) as the jammed device, covering the jammed device's signal with a very high power signal, making it impossible for the receiving device to interpret any target signal.

In fact, RF signal jammers were introduced for military applications and are used in high-risk situations, such as when bomb technicians are handling suspicious packages, to prevent bombs from being activated by remote controls.

How to Avoid Radio Frequency Interference from UHF/VHF signal jammers

In response to the widespread use of Radio Frequency Jammer in military applications, security designers have also come up with various methods to combat radio interference, such as using a large number of narrow-bandwidth signals with short bursts of transmission.
