When it comes to bandwidth vs efficiency it all comes down to how the bandwidth was achieved. Unfortunately, in most cases, a wide SWR bandwidth is the cause of losses in the system. The losses can be from the coax losses, or simply bad coax, or losses in the antenna system due to things like an inadequate ground plane. If losses are the cause of your wide bandwidth just remember, to much will hurt both your transmitted and received signals, and you likely won't even know it is happening.

There are other things that can widen bandwidth, so it is possible to widen the bandwidth of an antenna to a point with minimal effect on efficiency. Operative words here are "to a point".

Unfortunately some people see their antenna with an excessively wide bandwidth as a good thing, and to often they don't know that it is actually hurting them.
