Question 1

What is VSWR and why does it matter?

Accepted Answer

VSWR (Voltage Standing Wave Ratio) indicates antenna/transmission line matching. 1:1 is perfect, under 2:1 is acceptable for most applications.

Question 2

How do I calculate path loss for RF signals?

Accepted Answer

Free space path loss depends on frequency and distance. This calculator uses standard formulas to estimate RF signal attenuation.

Question 3

What is dBm and how do I convert it?

Accepted Answer

dBm is decibels relative to 1 milliwatt. 0 dBm = 1 mW, +30 dBm = 1 W, -30 dBm = 1 μW. This converter handles RF power unit conversions.

Question 4

When are RF calculations needed?

Accepted Answer

RF calculations are essential for antenna design, wireless system planning, radio communications, and ensuring compliance with regulations.
