#1 Post by natishamuros » 20 Aug 2015, 22:24

what is difference of 433MHZ and 868MHZ ? jammerinthebox says they both are remote control jammers

In terms of physics, generally, signals with longer wavelengths travel a greater distance and penetrate through, and around objects better than signals with shorter wavelengths.

Higher frequencies result in shorter wavelengths. Technically 433 MHz can travel a greater distance than 868 MHz.

433MHz Jammer is better in terms of distance, because it has low frequency means high wavelength. And according to physics of transmission, high wavelength travel long and penetrate through walls. So 433MHz is better than 868Mhz.

@natishmuros

There is a major difference of their capacity, 433MHz jammer is better than 868MHz jammer in terms of distance capacity.

In the US jamming Radio Frequency devices is not legal. Most high end 'drones' here use 2.4Mhz as in "Devo F12E 12-channel 2.4GHz Direct Sequence Spread Spectrum transmitter with built-in 32 channel dual antenna FPV receiver for 5.8GHz telemetry" Some controllers allow you to switch out the transmitter to lower frequencies for range enhancement at a price.

In the U.S. when caught interfering with radio frequency device operation:
significant fines (we call them “monetary forfeitures”) – up to $16,000 for each violation or each day of a continuing violation, and as high as $112,500 for any single act;
government seizure of the illegal equipment; and
criminal penalties including imprisonment.
The sale, lease, importation, distribution, or marketing of jammers in the U.S. or its Territories is prohibited by federal law. See 47 U.S.C. § 302a(b); 47 C.F.R. § 2.803(a).

Hi, maybe I'm too late to give an answer. The fact is that many car remote controls use 315MHz, 433MHz & 868MHz frequencies. For example, where I live, Italy, FIAT cars use 315MHz while 433-434MHz and 868MHz are used by BMW's and Benz's. Those frequencies are also used by garage door remote controls, gate remotes, etc. For a jammer like this, you can check here if you want 315-433-868 MHz Car Jammer

Yes, exactly. They are both remote control frequencies. Another remote frequency is 315MHz. In Italy some car keyless remotes use that frequency, as well. Those frequencies also manage garage door remotes, gate remote controls, etc.
