Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Antenna Diversity: You are in a Rayleigh fading environment where the distributionon signal power P (a random variable) at an antenna is ae^(-ap)u(p) for a some positive real constant and the powers of antennas separated by a few wavelengths is independent.
What is the minimum number of antennas you need have probility q that at least one antenna has a power level above Pmin?
