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.

How can I figure out what type of antenna (e.g.
omni, Yagi, parabolic, etc) I should use to
increase my SNR to an 802.11n router signal to
which I do not have line of sight? A straight
line running between the antennas would run
through approximately 30 m of interior
construction. With a 1 dBi antenna the noise is
at about -92 dB while the signal can range
between -70 dB down to -90 dB and the link is
frequently lost. How can I figure out how much
gain on my antenna would be appropriate, 6 dBi,
12 dBi, 15 dBi, and what pattern would be
I’m an EE but I have no RF
experience and I'm looking to learn more about
how to make such decisions.
greatly appreciate your advice or any references
or tutorials you can point me to.
