C-Band Satellite Dish Examination

A friend purchased a house in Eastern Melbourne and there was a C-Band mesh satellite dish mounted in the rear garden of the property. I was asked to determine if the satellite dish was in working order and then what TV channels where available.

Blind Scan of the Dish

The first task I suggested was to assume the dish was in working order and connect a DVB receiver and run a blind scan. This required connecting the receiver to the f-type socket in the house. I then connected a television to the output of the receiver.

I created a video of my attempt to blind scan the satellite dish.

This is a diagram of the configuration of the receiver. The satellite signal is forward from the satellite dish down to the DVB-S2 receiver. I inserted the Satellite Finder and connected a television to the receiver.

The DVB Receiver used to perform the blind scan was a Strong DVB-S2 model. I connected the component outputs of the box to the analogue television.

I purchased a Satellite Finder on ebay for $6.55 and inserted this between the DVB-S2 Receiver and the wall f-type socket. The meter has a scale of 0 to 10 and is illuminated for night time usage. There is an audio buzzer that indicates the detection of satellite signal too.

Lyngsat Research

After the blind scan was successful it was time to go over to the computer and check the Lyngsat online satellite listings for the detected Free-To-Air channels. From the online listing we will be able to determine using frequency details which satellite the dish is pointed at.

I chose to start my research using the North_East_Live channel that was displaying English titles. This channel was broadcasting on 4164MHz in a Horizontal polarity.

A Google search found that the channel is listed on the Lyngsat website.

The frequency and polarisation for North East Live matched our blind scan. This suggests we are watching North East Live on AsiaSat 4.

Clicking on the above link for AsiaSat 4 we find the 5 channels detected via the blind scan. Unfortunately it also confirms that there are no other Free-To-Air services on this C-Band satellite. This was a most disappointing discovery.

Received TV Channels

Before disconnecting the DVB-S2 receiver, I took a photo of each of the 5 TV channels that were received on AsiaSat 4.

I suggested to the owner of the satellite dish that it may be worthwhile to have the dish adjusted and pointed toward AsiaSat 7 as this C-Band Satellite carries a large range of Free-To-Air TV channels.
