Microwave ovens/microwaves, as the name suggests, use microwaves to cook rice. A microwave oven is a modern cooking hob that uses microwaves to heat food. Microwave is an electromagnetic wave. The microwave oven is composed of a power supply, a magnetron, a control circuit, and a cooking chamber. The power supply supplies approximately 4,000 volts of high voltage to the magnetron, and the magnetron continuously generates microwaves under excitation of the power source and is coupled to the cooking chamber through the waveguide system. Near the inlet of the cooking chamber, there is a rotatable agitator. Because the agitator is a fan-shaped metal, it has a reflection of the microwave in all directions after being rotated, so that the microwave energy can be evenly distributed in the cooking chamber. The power range of a microwave oven is generally 500 to 1000 watts. Thereby heating the food.
1. Why fiberglass antenna is not suitable for indoor use? A: Many people may have noticed that international brands such as Linksys or DLink typically use only 7dB, 5dB and 2dB antennas, while 9dB or higher gain indoor omnidirectional antennas are rarely seen in the market. As far as we know, the 7dB antenna has fully met the requirements of indoor use. The antenna above 7dB has been used. Due to the small Angle, it cannot give full play to its advantages. Therefore, we recommend using an omnidirectional antenna above 9dB for outdoor use. As for someone, it is good to say indoor wall effect, this statement is unable to prove, also need not believe too much. 2. Why are omnidirectional antennas and perpendicular angles called? A: Generally speaking, an omnidirectional antenna is an antenna with a horizontal radiation Angle of 360 degrees and a vertical sector. The Angle is usually around 6 ~ 15 degrees. The higher the gain, the smaller the vertical Angle. For example, the radiation Angle of the 9dB antenna can be about 14 degrees, while the radiation Angle of the FRP antenna can be about 8 degrees as the limit
