The Inflatable Punching Bag is designed on the principle of a tumbler. The exterior is made of PVC and the interior is inflated, which not only ensures the toughness of ordinary sandbags, but also buffers the instantaneous impact of hitting. It perfectly solves the shortcomings of traditional sandbags.

Features of Inflatable Punching Bag:
1. The P&D inflatable sandbag abandons the traditional hard sandbag and adopts an internal inflatable design. The gas squeeze can buffer the pressure caused by the sandbag opponent and avoid hand injuries;
2. The traditional suction cup sandbag will damage the floor and cause the floor to fall off. The inflatable sandbag adopts a water-filled base, which does not hurt the floor;
3. Made of thickened PVC high-density material, strong and wear-resistant;
4. The P&D inflatable sandbag is portable and suitable for multiple scenarios, allowing you to enjoy the feeling of free movement anytime, anywhere, and is no longer bound by traditional sandbags.
COFDM is a very advanced technology in the field of wireless transmission. Its main function is to transmit high-definition audio and video signals quickly and stably in a mobile environment with blocking. Its biggest advantage is to support applications that break through the line of sight limitation. Shooting power and penetration are the core of its technology, and it has good immunity to noise and signal interference, so it is very common in modern wireless transmission applications. But although COFDM performance is so powerful, it will still be affected by some factors in practical applications. Let's take a look at it.
1, antenna gain
In COFDM mobile wireless video transmission equipment applications, when the transmitter uses a high-gain directional antenna, it can significantly improve the power density (field strength) in the communication direction, and the receiver can significantly improve the signal/noise when using a high-gain directional antenna. Than, and increase the receiving field strength, thereby greatly improving the communication distance.
2, obstacle blocking
COFDM mobile wireless video transmission equipment has the ability to diffract, but the diffraction will cause the transmission signal to be weak, so the closer the obstacle is encountered, the closer the transmission distance of the equipment is.
3, the power of the device
Generally speaking, the transmission power and conditions are certain, the greater the power of the COFDM mobile wireless video transmission device, the farther the transmission distance is.
4, the same frequency electromagnetic signal interference
Although COFDM mobile wireless video transmission equipment has a very strong anti-interference ability, its transmission distance is also affected by signal interference of the same frequency.
5, altitude
Due to the curvature of the earth, there will be a certain drop in the transmitting and receiving ends of the device as the distance increases. Therefore, the distance should be adjusted according to the altitude during long-distance transmission.
