Doing a performance tests is sadly not an easy task. In general, the sensitivity of an receiver not the only parameter which decides if the whole performance is good or not. In case of terrestrial receiption there are some other influences on the signal and these made the task for the receiver also not so easy. The signal usually contains also fading effects, co-channel and adjacent channel interferers, all of noise influences and local generated distortions by your PC. And some devices are good with the one influences, others are good with other reception conditions. So if someone would test some receivers on this antenna this would represent only this signal condition, if yours is different, the whole ranklist could be different. But to test the devices completely with the usual influences, you need some expensive signal generators and a lot of time. So i never seen a test in a magazine where this had been done completely. If you are interested in such tests, with the keywords "NORDIG" (or "MBRAI") you will find some measurement standards on the net. In my personal experience, the differences between the devices are most time very small and i could not recommend a device which is better than all others.
