What does a very high SWR reading mean?
The antenna is the wrong length for the operating frequency, or the transmission line may be open or short circuited
A high SWR (e.g., > 3:1 or much higher) indicates a severe mismatch. This could be due to using an antenna far from its resonant frequency, or a fault like an open or short circuit in the feedline or antenna itself.
