VHF indicator, whose full name is vertical and horizontal filter in English and cross filter line indicator in Chinese, is a trend indicator. Different from the commonly used indicators such as MACD, RSI and KDJ, this indicator is not used to prompt overbought or oversold, strength or weakness, but to judge whether the current market is consolidating or unilateral, and to prompt investors to adopt the operation method of chasing up and killing down or throwing high and sucking low, which is very helpful for investors to choose aggressive or conservative strategies in different market stages.

Communication terminology

VHF refers to radio waves with a frequency band from 30 MHz to 300 MHz.

High and low frequency division:

Extremely low frequency 3-30hz.

Ultra-low frequency SLF (ultra-low frequency) 30-0.3khz

ULF (ultra-low frequency) 300-3 khz.

Very low frequency VLF (very low frequency) 3-30KHz.

Low frequency LF (low frequency) 30-0.3MHz

Intermediate frequency MF (intermediate frequency) 300KHz-3MHz.

High frequency 3-30 MHz.

Very high frequency VHF (very high frequency) 30-300mhz.

UHF (Ultra High Frequency) 300-3 GHz.

UHF SHF (Ultra High Frequency) 3-30GHz

EHF (very high frequency) is 30-300 GHz.

Very high frequency (VHF) is mostly used in radio and television, and it is also a communication channel for aviation and navigation.

VHF is mainly used for short-distance transmission. Unlike high frequency, the ionosphere usually does not reflect VHF signals, and VHF signals are often affected by environmental factors (such as topography).

UHF and VHF are two different bands on TV.

There is also V-L, which is the three frequency bands of TV.

There are different TV programs in different bands.

Now only color TV has three frequency bands.

Only black and white, no V-L.
