Why do I want to measure SWR with my SWR meter?

Your SWR (standing wave ratio) meter looks at forward (used) power and reflected (wasted) power as a measure of antenna system efficiency. This basic measurement has been used for decades to indicate “good” versus “bad” antenna operation, but it is actually an indication of the match between the radio and the feedline at a given frequency. 254 kata lagi

Ne sunt necesare un SWR-metru si un cablu de legatura. 324 kata lagi
