Have a couple bits of kit to check out antennas and feedlines.
The TDR is sort of like a sonar looking down the feedline/system for anomalies.
The bigger analyzer is newly acquired and small is one I have been perfecting “operator error” for some time.
I have a couple project antennas, a couple purchased antennas and a friend who has suggested I might help him with his problem antenna, so I guess it is time to brush off the user manuals and get ready.
