Wireless problem

Hi,

I am trying to connect my back shed to my house using a set of Borg ingot's.

The SL distance from my house to the shed is about 60-65 meters + or - 5m

I am using a DI 614+ wireless router as the main AP and using a DSE cheap PCI card on the other end.

I have used my PDA and am able to get a signal from both antennas but i cant get them connected together.

I have some pics but i know this BB does not support uploading pics.

Also is it better to mount the antennas upright or horizontal?

Borg Ingot
Frequency: ~ 2.437 Ghz (optimal centre frequency)
Gain: 5-9dbi (estimated at this stage until the confirmed figures arrive)
VSWR: 1:1.2 (estimated at this stage until the confirmed figures arrive)
Polarization: Vertical or Horizontal (dependent on what way it is mounted)
Beam Width: 10° to 15°
Connector: N Female
Dimensions: 100 X 50 X 20mm
Mounting: U bolt for Horizontal Operation (Optional Vertical mounting kit available)
Material: AL

might be an idea to try and connect them together without the external aerials, and see if its a software problem rather than the aerials themselves...

I have a shed which houses my AP which runs an Omni monopole (about 6-8dBi)on a bamboo stick 1.5 metres above my shed roof. I use a directional antenna connected to my laptop card and have no probs. I have also used a cantenna in the same position aimed at my house with good results using only my laptop card. You also might need to take into account that your house may be blocking the signal, especially if it was built 20 years or more ago. They used aluminium sisalation then rather than the tyvek-type paper used these days. I agree with etienne try and network the card and the AP in close proximity to rule out software probs. check to see if u are setup as ADHOC or INFRASTRUCTURE.

Hi ok i managed to get the pics on the web

Shows the antenna on my roof



Shows the antenna in the back from the window in pic 2
ignore the other antenna it aint mine


Shows the antenna at the back.
I dont know if it should be mounted horizontally or vertically?



as u can see the antennas are all external.

It is a kinda bridge to connect the internet at the back to the house.

You may have stuffed the charecteristics with the holes you drilled into the wave guide.

Also, both should be horizontal or vertical and open ends pointing to each other.

Man - you should call shadowX on this - it looks like a very suss install....

i didnt drill any holes into the antenna. The antenna has them the screws are just a temp to try see if i can even get the signal

yeah the install is suss but it is just temp atm till i can get a decent signal to the other side then i will start with the proper mounting and masts

Tide,

I see your problem....

The opening that has the warning lable on it is the end that the signal comes out of not the face that BORG is written on. this is the face that needs to be aligned to each other (or atleast pointed in the general direction.

They also have to be in the came polarisation. The screws are OK where they are and we provide the holes so you can mount the antenna on a normal hocky stick type antenna mount using a standard size V clamp (or u bolt)


So what you should have (and please excuse my ascii art)

[GROB] <-> Transmission path <-> [BORG]

Both ingots have to be int he same polatisation (within reason) If one is horizontal then the other also has to be, if one is vertical then the other has to be verticle. The second picture you supplied is horizontal polarisation.

Part of your problem will be that the one in the forst picture is pointed at the ground, also im not sure if it is just an optical illusion but the other one seems to be pointed at the roof of the shed. Both transmissions openings should be able to see each other.

Hope this has helped some.

thanks shadow i just figured it out from wifi guys post last night.

yeah for some reason i was thinking that it worked like a panel not as a directional antenna.

Works now

cheers guys

Once its all set up and permanent i would be interested to get some feedback on your install and what sort of signals, connection and pin times you are getting.

ok i been testing it today and it is working but the signal strength is very weak and keeps dropping for some reason.

I tried to adjust the antennas but it makes no difference to the signal level.

I seem to get the signal at a resonable level from the house mounted antenna to the shed using my laptop and a PCMCIA Card with a built-in antenna. I then moved the ap to the shed antenna thinking that it may have been the pci card but it seems that the shed mounted antenna doesnt work as well as the house one.

Tomorrow i will try and get some net stumbler stats from both ends.. and will post.

hopefully it aint the antenna but is there anyway i can test it shadow?

excellent work Tide - shadowX is the man...

Do a comparison on the two antennas. I did test them both before they left but if the courier decided to play football with them then there is a chance that one may have been nudged out of tune.

Swap over your cables as well. I have seen issues where the cable has not made contact.

Basicly the easiest way to test is to pick a referance point somewhere in front of the antenna. then take a readint from there. Swap over the antennas then compare the readings. Then swap over the cable and compare the readings, then swap back the original antenna.

you really should not be having a problem over such a short distance. Something else that needws to be noted is the beamwidth. It looks to me that the antenna on the house is actually fixed to the house? But the one on the shed is fixed to a peice of fencing battern. Guessing its something like 150 X 15. there is a lot of flex in this and you will find that it only takes a little bit of wobble before the antenna goes past its usable front lobe.
