The SNR you quote, which improves as square root of the collected radiation (radio waves), is voltage SNR. In terms of power, you still get a 9dB SNR improvement for 3 times the collected radio waves, and in these electronics, it is electric power which is the ultimately used. However, the improvement factor should again be raised to power 1/3 to get distance, since the amount of signal power collected by an aperture, after spherical dispersion from a star, drops as the third power of the star's distance. So.. (25/9)^(1/3) = 1.4 times.
What should be the absolute heart of slashdot, two new releases of Linux, sporting different styles, is getting some 30 posts for BOTH distros combined,

Apple had acknowledged to Congress last year only that "cell tower and Wi-Fi access point information" is "intermittently" collected and "transmitted to Apple" every 12 hours.
Citation? I don't doubt you, but just because you type it does not make it true. Especially in the auspices of someone who decries fanboi-ism, I'd expect to see an avoision of even the appearance of impropriety in fact-reporting.
It is supposed to happen only if location based services is toggled on and an app that requires location data is running. http://www.wired.com/images_blogs/gadgetlab/2011/04/applemarkeybarton7-12-10.pdf , Page 7.
