Question: Will this antenna (insert antenna description) work with my 802.11b network?
Answer: In order for an antenna to work properly with a wireless network, it must be tuned for 2.4 GHz (for 802.11b) or 5.3 GHz (for 802.11a).
In particular, quite a few people have asked if a CB radio antenna (like one found at RadioShack) will work with their 802.11b network. The answer is no. The CB radio is tuned for use in a different frequency, and is not compatible.
RTFM - Always a good idea
