Lining up Yagi wireless airiels (best practice)

Hello everyone,

Over the past few months, I have installed several WLAN's using Cisco YAGI antennas. They seem to be a nice piece of kit to work with. Although, because they are fairly directional. Most of my install time is spent lining them up correctly...

I can't help thinking there must be something better than two guys on the end of a ladder with 2-way radios!? left a bit!, right a bit!, down!!! :)

How do the rest of you do it? Are there any special tools for the job?. Maybe a laser alignment tool of some kind..

I know that you can measure the signal strength in ios by using debug commands. But it's all a bit too late by the time your at the bottom of the ladder!.

I look forward to your responses.

Kind Regards & Thanks

Matt

This is where a GPS and good compass can be your best friends.

Go to site A, take a snapshot of that location (save the location). Then go to site B, and tell the GPS that you want to "goto" site A .... it'll give you a bearing (some will give you an arrow pointer).

Set the site B antenna to that bearing. Most GPS can also give you a decent altitude reading to help with "elevation adjustments.

Take a reading / snapshot of the site B location.

Go back to Site A and set that antenna to the Site B bearing (and possibly elevation).

Use the RSSI indications to tune 'em in as necessary / if necessary.

I know some folks that put a rifle scope on the boom of the yagi and aim for a strobe attached to the other antenna.

Whatever works ...

FWIW
