How does frequency affect your choice? 1. Frequency is an important consideration. 2. Loss increases as frequency is increased. 3. Always calculate loss at highest operational frequency. 4. Chart opposite shows loss per meter. What is db? - The decibel is a relative unit of measurement.1 db = 1/10th of a bel. - The decibel measures the relationship between two quantities in the same units (Watts, etc). - It is defined as ten times the common (Base 10) logarithm of the ratio. - Formula X in db = 10*Log(Quantity 1/Quantity 2). - db can be used to express a change in value(e.g., +3dB or -3 dB) or an absolute value.
