Surprisingly, I am unable to find much info comparing these two antennas. Essentially, they are the same except the one is shorter and top loaded with one wire. Does anyone have any performance data available? The basics I know is that the 1/4 wave vertical will have a lower angle of radiation, but is there any difference in efficiency? Will the 1/4 wave actually have worse local performance than the L?
It would be a major expense and work to install, so I want to know the worth. Maybe even just personal anecdotal evidence.
In addition, I notice an interesting phenomenon. I currently have a 70ft inverted L. I compared to similar low power MW stations because they are 100% duty cycle, so I can see the effects more clearly. What is interesting is that my signal under good conditions, seems to reach a higher S level (listening through MW SDRs), but under bad conditions, it is worse than the MW station. So it has higher highs, but lower lows. I wonder what causes that? But either way, it leads me to believe that I won't have much better performance, just higher reliability. This is just one comparison however, so it could be in the noise :)
