There are no interesting antennas laying around so lets look for new hardware.

LATVIA is maybe a good place to life and study - the home of Mikrotik OS and their routerboards a new company is bringing new open router board.

Open embedded hardware bring us open software solution for wireless networking. They deigned small router board based on PowerPC cpu running on 266 or 333MGhz, 2 mini PCI slots, 2 LAN, 8MB flash, compact flash and up to 512 or RAM. /info about system specs is from openrb site and video on tube from cebit/

There are two interesting things here - folks from openrb says that software will be FREE and other thing is that You may be will be able to choose hardware configuration for your router. Mentioned price is not so good, its around 100 euros for full configuration of the board.

So everything looks good on paper will be great to have one more company building quality hardware.

Bad thing is that they do not yet sale this. We will wait and see will this new open router board will be born.

And one last thing using only open source they can’t get all goodies of payed OS, so maybe hardware is not all.

This is really good collection of wifi antennas posted on El Rincon de ToPaChoxXx

Go on hes site and get it !!!

41MB archive file with all kind of antennas inside - THIS IS REALLY MOST INTERESTING THING for last two or tree weeks!

One more time - do not miss this

Here one very interesting antenna - La Fontenna Clone.

It was interesting what is inside FON antenna. On site specs they give it 7dbi or 6.5dbi with 3m low loss coax.

On one Italian blog I found dimensions for building a clone of La Fontenna.

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 :

We haven’t heard too many specifics when it comes to performance of actual WiMAX rollouts (and let’s be real, we’re all kind of waiting for LTE at this point, right?), but Garth Freeman, CEO of Buzz Broadband, apparently shuttered the company’s Australian WiMAX rollout in Hervey Bay, publicly declaring that for his company and customers the technology “failed miserably”. Apparently beyond about a mile from the base station non-line of sight performance was “non-existent”, regular indoor use produced latencies as high as 1000ms even just 400m away, and the company had to scrap its network for TD-CDMA service on 1.9GHz just to make sure customers weren’t completely left in the cold. Maybe they should have checked for an errant satellite, eh mate?
