Thanks

These designs are reprinted with the permission of Kent England WA5VJB.  They appeared in the March 2008 issue of Popular Communications.

For those of you looking to get good airband reception in a particular direction, these antennas should work wonders for you.  And they are very inexpensive to build.

Enjoy - and you can find more designs and info at http://www.wa5vjb.com (currently in the process of changing DNS so try tomorrow).

One of my friends makes Yagi's. He currently has the desighn for military air, but VHF will be out soon. He has picked up (DX'ed) ground stations from over 175 miles away. They have a 9.8db gain. Scroll down to watch the video. This guy has the best milair setup I have ever seen. He is the best milair antenna maker by far.

Also, if you live in a less populated area, you may want to try a preamp. This is the same company that makes it for NASA www.AngleLinear.com

Yagi's are great for ATC, and air. They will do the BEST job.

Is anyone interested in a 10 element yagi or log periodic antenna for the VHF air band?  I've been experimenting with some java number crunching programs, and worked out data for two such high gain antennas.  If you're interested in a particular airport or ATC sector that is hard to receive, one of these antennas could improve reception.

Here's the link: http://www.ab9il.net/aviation/airband-antenna1.html

The idea for an air band project came after enjoying good results with similar wi fi and FM broadcast antennas; 10 elements is about as large as practical for the aviation band.  Beyond that it makes more sense to just locate a receiver closer to the action.

Regards,
Phil
