! The following is an overview of NodeGLT:



!!! Current Status

* Currently in testing mode.

* Running Access Point 24/7

* Set Access Point SSID as "NodeGLT"

* Set the AP to Channel 1

* If you can connect to my AP please email me:





!!! Access Point Information

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

http://www.svec.com/PRODUCTS/wireless/FD1811.asp



The AP was purchased through the Melbourne Wireless TIB, see link. http://www.melbournewireless.org.au/tib.php



!!! 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.

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

I have found the plotting features of the www.nodedb.com site useful, for this reason I have also registered with this site, see link below for further details.
