Ultra High Frequency - Advantages and …
The main advantage of UHF transmission is the physically short wave that is produced by the high frequency. The size of transmission and reception antennas is related to the size of the radio wave. The UHF antenna is stubby and short. Smaller and less conspicuous antennas can be used with higher frequency bands.

The advantages of contact type high frequency welding machine welding are: 1) Less effective splitting; 2) High current density and high efficiency due to the proximity of the contact head; 3) Small thermal influence range; 4) Small influence of pipe diameter, weldable pipes with a diameter of about 8 to 1270 mm; 5) Welding speeds of up to 100 to 120 m/min. Such high welding …
Low Versus High Radio Spectrum - High Tech …
Many people believe that radio frequencies below 1 GH are ideal for mobile communications, but while lower frequencies provide some advantages, as the industry increasingly has to deploy capacity-constrained networks, the differences between low and high frequencies become much less significant.
Advantages of high frequency PWM in AC motor …
Abstract: There are many advantages of using high frequency PWM (in the range of 50 to 100 kHz) in motor drive applications. High motor efficiency, fast control response, lower motor torque ripple, close to ideal sinusoidal motor current waveform, smaller filter size, lower cost filter, etc. are a few of the advantages.
High Frequency Skin Care Treatments Benefits …
The high frequency current produces a gentle spray of oxygen molecules that penetrate deep into the areas that are affected by blackheads and enlarged pores. They clean out all the debris and toxins, control sebum production and soften up the skin, which eliminates the blackheads and reduced the size of the enlarged pores.

Pros and cons and differences of a "low …
High frequency power inverters typically drive the transistors at a high frequency closer to 50 KHz or higher. When delivering the same amount of power, for example, the 6KW low frequency inverter transformer outputs more power at each cycle, so it is required to work harder, resulting in larger and heavier transformer and package. In contrary, a 6Kw high frequency inverter …
