ACCESS POINT INFORMATION
I am currently using a SVEC access point, see link.

The AP was purchased through the Melbourne Wireless TIB, see link.

ANTENNA
My antenna is an Omni directional homemade using LMR400 cable and
based on an article at the following link:
http://wireless.gumph.org/articles/homemadeomni.html.
For properties of the LMR400, see link.
http://www.timesmicrowave.com/telecom/pdf/LMRGuide.pdf
I used the following to calculate my sector length for the LMR400:
* V = velocity factor of LMR400 = .85
* C = speed of light = 299792458
* F = frequency of signal midpoint = 2441000000
* Calculated 1/2 wavelength as 52.19mm and based my construction on
this sector length.
Cable loss from Access Point to Antenna is calculated as follows:
* 150mm of LMR195 = .1 dB approx. (19dB / 100 ft = 19dB / 30480mm =
.0935dB / 150mm) plus
* Connector = .5 dB approx. plus
* 2300mm of LMR400 = .5 dB approx. (6.8dB / 100 ft = 6.8dB / 30480mm
= .51 dB / 2300mm)
Total Loss = 1.1 dB

My node id in Melbourne is as follows:
349 - via www.nodedb.com
GLT - via melbourne.wireless.org.au
MUST DO!
* Interested to contribute to getting an effective wireless network
operational in our area.
