estqwerty’s wifi antennas

Saved long long ago from an old Russian forum: wifi-connect.ru

The site is running now again, but without a forum, and no new info is available.

(more…)

This is just a bigger version of previous coax antenna.

There is no info available about gain or anything els.

Used coax is RG-213

On site also suggest some sort of franklin dipole :

I thing that this design will be fun to test.

May be will work ? What you thing ?

Found on http://www.zero13wireless.net/foro/showthread.php?t=3964

I cant find original site of this antenna there is links on Zero13wireless forum.

I cut a lot of coax without any success before time in attempt to make a coax omni antenna.

This thing here is looking different. But maybe will work.

This is the idea :

30mm in the beginig 1/4 wave - may be patching section.

40 mm of outer of coax is used to dephaseing sections.

60 mm sections as 1/2 wave radiators.

And that is.

I can’t remember direct link to site from where I found this pictures but on them is writhed on them :
