After purchasing our wireless jammers, some customers took out several antennas that matched with them in the process of preparing for installation and found that many antennas had the same shape, so the customer's question came: why the same wireless jammer Are the antennas the same? Are they interchangeable?

Let’s talk about the answer first: Although these antennas are very similar in appearance, they are actually different, and basically they are not interchangeable.

If customers carefully identify the antenna, especially at the end of the antenna, there are usually obvious signs. These signs generally include: port serial number, operating frequency range, standing wave ratio and antenna gain value, etc.

At the same time, if the customer checks the mainframe of the wireless jammer again, he will find that there is a very conspicuous port serial number near each RF output port of the mainframe. This is to clearly inform you that each antenna must be connected in a one-to-one correspondence with the port number on the wireless jammer host. The order must never be reversed or confused.

Each antenna has its fixed operating frequency, and only when the RF port is connected correctly can it play its best performance at the corresponding frequency. When the corresponding connection is made at will, because the operating frequency is not suitable, the consequence of this is that the antenna may generate signal self-excitation and cannot output power normally, which will further lead to energy accumulation, overheating of the interface, or direct damage to components such as power amplifiers.
