estqwerty’s wifi antennas

You can read about this antenna here www.g0mrf.freeserve.co.uk

Freq : 5.6Ghz Gain : 10Dbi Beamwidth : 55 deg

All building instructions are on the site.

Here is the scans of inside - very thin pcb board is used.

Some time ago I needed some 5ghz antennas - this is the first thing that I bought.

Dual-band 11a/g 7/5dBi Indoor Omni Antenna from trendnet.

The papers says :

The stupid thing is that on the site specification and in pdf data sheets was said that this antenna have VERTICAL polarization, but now I can see that omnidirectional pattern came whit horizontal polarization!

This may be the reason why I am not happy whit this wifi antenna and it is still laying on my desk.
I will test it again when I have some time.

The other small wifi antenna that I have from trendnet is working great - I have small 5ghz link whit it - these days maybe will scan ti too.

Here is my collection of pictures of PAC Wireless 5ghz feeder.

Please If Anyone have idea what design is used inside and have any pictures - send me a mail or post a comment or contact me.

Wow ! It’s a surprise for me to see that helical antennas are working so good on 5ghz to 6ghz band. Here is a company that selling them http://www.q-par.com/products/helical-antennas/5-6-ghz-helical-antenna

GAIN ~10 to 11.5 dBic by specification -who knows

So if You like to try 5ghz wireless links, You may try helical antennas . I’ll be waiting for results if someone try to build and test this.

Here is the picture of one of this - nothing unusual really:
