Antenna Gurus: Why seems to be missing in this picture?

6_6_6 · 09-01-2005

Hello Folks,

Here is the setup:

24 dbi parabolic grid antenna from Sharper Concepts. http://sharperconcepts.zoovy.com/product/YSC-HG2424G
7 dbi omni antenna.
200 mW Senao 2511 CD EXT.
HP Pavillion 8000 series 3.6 GHz 17" WS (Built-in Broadcom a/b/g minicard WLAN adapter)
2003 Server / Knoppix Dual Boot
Netstumbler / Kismet

With built in card, I am able to receive 2 of my friends' signals if I hold my notebook 1 meter out from my window. I can't receive any of them from inside my room.

So I went and purchased 200 mW Senao PCMCIA card and 7 dbi omni and 24 dbi parabolic antennas in order to be able to receive the signal from my room. Unfortunately none of these antennas receive these signals from inside the house even next to the window. The only time they would receive it is when I place the antenna exactly at the same spot where my built-in antenna is catching the signal.

My house is on first floor and there is an adjacent building where my window is facing.

With these higher gain antennas, wouldnt I be able to receive the signal 1 meter inside at least?

I also went to my bf's house to check the setup. He is located at 20th floor. With built-in card, I am able to receive public access points about 10 cms outside his window. But placing both 7 dbi omni and 24 dbi parabolic inside does not do any good and I can't receive the signal there inside the house either. I can only receive the signals when I extend the antennas outside the window (same place as the built-in antenna).

The strange thing is that none of these antennas are picking up more APs than the built-in antenna. Perhaps 1-2 more. His house is on a busy street and there are plenty of APs around.

Third check up from the roof of my building. 5 storeys high. None of these antennas pick up any signals stronger there than the built in antenna and they do not pick up more APs than the built in antenna.

Can someone give me an insight as to what I am doing wrong?

Also, the radiation levels... Just how harmful are these if you stay 1 meter away from them when they are working? Mobile phones disturb me (burning sensation inside my brain) so I dont use them and these antennas seem more powerful (burning sensation right after using them for a minute).

Thanks!

Maria

Newbie Lounge: The place to come to ask your basic NetStumbler/WiFi questions before moving on to the rest of the forum. This is the type of question to be posted in the antennas forum.

If you have burning sensations when using mobile phones and other equipment, I think you have more serious problems than trying to figure out why your antennas aren't working properly.

Streaker69, theprez98,

I would kindly request from you to post only ***PERTINENT*** responses to my question on my topic .

I just read some guy's question with 7 pages of unrelated gibberish on it and I don't want my topic to turn into that. It just looks like you started to drive it to that direction.

Anyone's help would be appreciated but you are not helping by doing like this. I hope I made this clear.

Thank you.

Maria

Don't worry. It won't.
