Core Node

Skye and Highgate will be down today whilst they undergoe routine maintance and upgrades, which will hopefully improve reliability and performance.
They should be back up later this afternoon.

Cheers,

I have a small quantity of chimney antenna mounts. These are all 'as new' condition. Very quick and easy to setup. No drilling required. Best and easiest way of mounting an antenna on older style houses.

I have used one of these at a setup for the last two years supporting a 3m tall mast with a 15dB antenna. It has proved to be strong enough to survive through the storms in winter.

Each kit comes with:
antenna Bracket
wire strap
wire clamp
x2 I-bolts
x2 U-bolts
x6 nuts
x6 washers

$15 each (normally around $33 at Bunnings)

Pickup from Seaton or DryCreek (depending what time/day)
Delivery *may* be available for little to no extra charge depending on your location and amount purchased

Air-Stream Grange is in planning and should be up later in 2008.

Currently it has a client link to Air-Stream Seaton.

A new pole will be installed which will hold the new installation. An 8db superpass omni antenna will be set-up for client access while backbones to Seaton and Glen Osmond are planned. Carrick Hill, Torrensville, Fulham Gardens and Woodville West are also possibilities.

Currently the site is waiting on installation of an AC outlet by a qualified electrician in the roof to make supplying power easier.

Latest image of the current set-up. this is the original pole that has been there since August 2004.

Skye has moved once again to have a new home approximately 600 Metres to the North East which not only provides good LOS to existing nodes within the network but also greater coverage and better redundancy between the CBD and northern suburbs.

Outages are expected to be mostly localized and may effect some North South connections between High Gate Park and Valley View as systems are bedded down.

SPLAT! is an RF Signal Propagation, Loss, And Terrain analysis tool for the spectrum between 20 MHz and 20 GHz. It provides site engineering data such as the great circle distances and bearings between sites, antenna elevation angles (uptilt), depression angles (downtilt), antenna height above mean sea level, antenna height above average terrain, bearings and distances to known obstructions, path loss based on the Longley-Rice Irregular Terrain Model, and minimum antenna height requirements needed to establish line-of-sight communication paths absent of obstructions due to terrain.

Below is the predicted LOS for OHalloran Hill, it assumes both up and down tilt and no signal path loss, only path obstruction.

These installations are to be considered the property of Air-Stream Wireless Incorporated, and are carefully administered under the guidance of the Network Team, to comply as closely as possible to the Technical Documentation.

Referred to as 'Core Nodes', they are designed to create a reliable backbone of connections upon which all other Air-Stream nodes interconnect.

Air-Stream APs have the following characteristics:
