3 out of 5 eggsNo improvement

Pros: It's not worse than the stock antenna.

Cons: No signal strength improvement noticed. Expensive.

Other Thoughts: Installed on WRT54gl. I did not see any improvement over the stock antenna. I tested with a laptop and with hand held signal meters.

5 out of 5 eggsWorks

Pros: Worked the best

Cons: Very Pricy

Other Thoughts: We tried many of the <10db omni antennas around the plant. For whatever reason, these work out the best as far as user experience. Hawking, Linksys, dlink all have similar specs, but in actual use, this antenna had the least number of user issues. We did not inform the users of which antenna they were connected to at any given moment.

5 out of 5 eggsReally Works!

Pros: Increases the range of our wireless network enough to shut up annoying users!

Cons: Looks like a white paper towel tube.

Other Thoughts: Great idea! I put white paper towel tubes all over our warehouse and made about $318.00 in overtime!
