I thought the "Q" of the antenna was not vry good since the SWR curve is vry broad.
Q means many things. Some things might be good, some things might be bad, and some things are just meaningless.
SWR bandwidth by itself does not tell you a thing about antenna efficiency or performance. SWR bandwidth is SWR bandwidth, nothing more or less. A narrow antenna can have terrible efficiency, and a broad antenna can have great efficiency. It can also be the other way around.
Beware of anything equating radiation performance to SWR bandwidth. _________________ Topband Reflector
