The semi shielding structure is adopted, which greatly suppresses the electromagnetic clutter interference in the external environment, improves the dynamic range of the entire system, and is conducive to improving the detection accuracy of the position.Small and practical: The magnetic field antenna is small in size, compact in structure, good in stability, easy to install and easy to use, and is a practical accessory.Large heat dissipation: The PCB near-field antenna has a large heat dissipation area, and has a longer service life and longer service life. So we believe that you will feel at ease with the product because of its stable functionality.Easy to use: The electric field antenna is very reliable to find interference sources, with high precision, high resolution and easy to use.PCB near field antenna with good current flow,With high performance, the electric field antenna is definitely your best choice.Type: ProbeFrequency range: 9KHz-7GHzLarge (Type III): The probe part has a width of about 2.5cm, a thickness of about 2.3mm, and a length of about 10cm.Colour:blueMaterial:PCBPackage Contents:1 * Large ProbeOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
