Òdinè ki pa ba kab nan, pou egzanp, SYV-9-50-1, 900MHz β koyefisyan diminisyon = 20.1dB / 100m, ki ka ekri tankou β = 3dB / 15m, se sa ki, yon frekans nan pouvwa siyal 900MHz, Apre chak kab 15m tan sa a, yo pral pouvwa a ap mwatye!

The ordinary non-low cable, for example, SYV-9-50-1, 900MHz attenuation coefficient β = 20.1dB/100m, can be written as β = 3dB/15m, that is, a frequency of 900MHz signal power, After each 15m long this cable, the power will be halved!
