Finally, my node is active!!!!
It is one of ShadowX's slotted waveguide on top of the ihug building facing west.
It covers a damm large area.
No internet offered as yet (no plans to either) however I do intend to get dchub and an ftp/http file server online soon.
If you live west and can connect, or are in the area and have a chance to attempt to connect, I would appreciate comments in this forum, in particular antenna type, card type, signal, noise, etc.
D-Link 900ap+ Access Point (17dBm)
ShadowX (Borg) 8 Slot Waveguide (18dBm)
SSID cbd.johnburns.nzwireless.org (SSID transmit enabled)
Access point IP 10.23.28.254
DHCP range 10.23.28.1 - 10.23.28.50
Its not too exciting as yet as its just an AP however with a nice large area of west auckland It should be in a useful spot.
Roll up, Roll up!
Antenna will have a modified camera flash strobe on top of it, should flash from dark until about 1am or so.
One flash every 5-8 seconds.
If you live out west, get out your binoculars and take a peek.
Approximate position from west (te atatu ish anyway).
Take the distance between the skytower and the asb tower (tall building with lit up yellow ASB on top).
Go to the right of the ASB building for about 4 times this distance.
You should be looking at the newcall building. antenna is to the bottom right of the newcall building.
Try as I might, I couldn't see it. I was looking at an area where there were a bunch of buildings with red lighting on them. I think the ihug building may just be a bit left of there. Unfortunately to look at left of there I'd have to get on the roof, as Birkenhead is in the way when looking from the deck.
I saw it, and realised that my idea of what was where was a little out.
Either way, I now know where the antenna is which makes alignment far easier......
Does anyone know the best way to align these things?
My sky dish on the roof picks up the signal, albeit weak.
I then put a spare ap on my sky tv dish and thought that I could tap into the waveguide to align the signal for the downtilt this way - I can pick up literally 50 or 60 aps from its present position, just not mine.....
Maybe I'll rehash the parabolic dish feed to see if that changes anything.
Dont forget to take the polarisation into account. you may need to rotate the feedeer by 90degrees.
In theory a reflected signal has no polarisation but in practce i have seen it with a polarisation and have no idea as to why.
After mucking abour with a 60cm SkyTV dish and getting a signal too low for any decent use, I brought home a 90cm dish and mounted it on my roof, a little further out, with a better view of the city.
Coupled to this is my new high tech Liquorice allsorts can feed. I am now pulling in a -48dbm signal at the feed can - this goes as high as -40 but the lowest value was -48 over the last 6 hours.
Add to this about 12 metres of RG213 and the signal is getting a lot worse.
I hope to have an ftp server online shortly so all you people out west, pull finger and get to it! A wireless link is no fun with only 1 connection.
At the moment I am playing around with a 90cm dish and a tin can feed. The only issue is that I have a perfect signal at the dish (-30dbm!) but the length of rg213 I am using is a little too long.
I am in need of around about 15 metres of LMR400 which should fix the problem.
I tried tonight mounting a USB client on the roof and using 3 active repeating USB cables to connect to it but it doesn't like that.
I'm not too keen to be running a spare pc in the roof so at the moment I am on hold until I can get a decent length of cable.
In fact this is what I am looking at. I plan to use a 900ap+ at home in client mode - how reliable are they? Will I end up using 2 ip addresses (one for the ap in client mode and one for my pc?) or is the ap's ip address transparent when in client mode?
Either way, I will try this tonight with a *borrowed* ap and if I am happy with the results will buy one for the job.
