Digital SWR meter with 2-bit LED + Directional Couplers 1..30 MHZ & 144..146 MHz

Description

Digital SWR meter with 2-bit LED + Directional Couplers 1..30 MHZ & 144..146 MHz
3-in-1 KITs!
The SWR meter or VSWR (voltage standing wave ratio) meter measures the standing wave ratio in a transmission line. The meter can be used to indicate the degree of mismatch between a transmission line and its load (usually a radio antenna), or evaluate the effectiveness of impedance matching efforts.
A directional SWR meter measures the magnitude of the forward & reflected waves by sensing each one individually, with directional couplers.
- Completely automatic measurement process
- Microcontroller ATMega48.
- The inputs could be connected to the transmission lines in any order.
- The firmwire itself determines the direct and indirect channels.
- Displays the level in the SWR antenna-feeder tract digitally.
