Maybe I didn't convey in that post that I'm on top of the basics.
The point of the post was to relate how dramatic the effect of signal overload can be. It wasn't just a reduction in displayed aircraft or range, it was a drop from seeing numerous aircraft, some beyond 175nm to seeing virtually nothing. Virtually nothing was just one aircraft within about 15nm. It was way more dramatic an effect than I would have imagined.
Some additional learning points from this scenario were:
+ Don't assume an antenna is going to work well solely based on reflected power reading i.e. VSWR, however its a good sign that it will work to some degree
+ Range should not be used as the sole indication of antenna effectiveness, look at message rate and the number of 'hits' over a significant period of time
+ Finally, don't ever take something at face value, check it out
My 'fall back' and the 3 element co-linear I mentioned previously are shown below (original graphics as downloaded, not my actual versions).
