The one to which the OP provided a link isn't that cheap ($50) |
| 13 |
and gets universally excellent reviews. My testing indicates |
| 14 |
that it does indeed provide something on the order of the |
| 15 |
claimed 15dBi gain. It's performance is very close to that of a |
| 16 |
well-built double-biquad reflector: both show 10-12dB increases |
| 17 |
over a stock 3dB "whip" when I tested them with various bits of |
| 18 |
HW (a USB WiFi dongle, two different brands of WAP). |

That said, the cable on the Hawking unit is pretty flimsy -- |
| 21 |
and hence probably is rather vulnerable to both electrical |
| 22 |
noise or physical abuse. It probably wouldn't take much of a |
| 23 |
pinch or kink to cause problems. |
