Been there done that , 20 mile test , 102 seemed to receive a slight bit better , but not enough in my case to change over from my W-1000 at the time. According to my targets , they both trasismitted about the same. I'd bet to say from what I've read over the years , that 102 inch is more then likely the best that it gets , The Wilson is a decent bottom loaded antenna that works well and works well with power. It's a compact situation compared to the 102 incher , with much ease of installation.IM sure we will being hearing about the 10K in these parts next. I live in the big city , 102 inches is way to much for me anymore , (Ran a Fransis Amazer for a few years in the 90s) I'd like to run a single coiled 10K one day , my only personal problem with that is the big city and having everybody and there brothers (and the man) looking at me everywhere I went. The 102's will do that as well in these parts. The Wilson works good enough for me for the last 15 years or so ,it's low profile and has a very nice look to it , doesn't really stick out like a sore thumb to speak. Bottom line for me is that it works good enough for me and that's all that really matters , I truly doubt I'd be missing much running anything else.
