Tools to allign Yagi antennas to each other

[malzub]

I have an implementation that requires me to point 4 Yagi antennas (two pair of building to building Bridges) and was wondering what would be the best way to align them and if there is an automated tool to do so. I know that the 1310 has an LED in the back to help indelicate signal straight, but getting the right angle to begin with is tough, specially that the two locations are 2 miles apart

Thanks,

Mohammed

GPS is a great tool for this.

Go to the first site and set a marker (waypoint)in the GPS.

Then go to the second site, get the antenna up and use the 'Goto " function .... it should put an arrow on the screen that points directly at the first site.

Depending on the distance, there should be enough beamwidth on the signal to capture it and fine tune the pointing with the local tools (signal strength meter, etc.)

Also, depending on the quality of the GPS, it should be able to give you an altitude readout at each point so you can adjust the elevation angle of the antenna as well (a little background in geometry wouldn't hurt either (slope over distance kinda stuff).

It's the only way to fly, trust me. If you want something visual, there are some cheap battery-powered strobes available ...

Good Luck

Scott

We use a combination of GPS, Netstumbler, and a rifle scope with a custom mount. The mount allows you to look over the antenna.
