Wi-Fi SWR Meter

Tuesday, November 20th, 2007

On the are updated page for building wifi swr meter. mcWit was able to find replacement of the BAT62-03W Schottky diode used by in his design. New diode is hsms-2822

There are several changes in the elements in due diode change. I can’t understand everything written on the site. But everything is there and all is build and tested.

Now just need to wait for more documentation.

Here is a picture of the finished device :

Poland Dipole Panel Antenna

Tuesday, October 30th, 2007

18 or 19dBi – no mater for this one 🙂 . Several dipoles printed on PCB board. Have more dipoles You get more dBis. Will it be 10 12 or 24 – You decide how much do You need.

This is defiantly homemade design. I have one small antenna whit only 4 dipoles – and it works great, so this antenna should work fine. Also will be easy to be rescaled for other bands – 2.4Ghz or 5Ghz only change dimension of the dipoles.
