IRS Calculator

Cable loss calculator

Drag the slider to set your cable length in meters

Distance: meter

Loss: dB

This result is based on 75 Ohm type 100 coaxial cable at 2150MHz

Satellite look angle calculator

If you don’t know your longitude and latitude, then click ‘Get current location’ to populate these values. More precise values can be obtained from google maps by a right mouse button click on your location. All geostationary satellites are located at the same height above the equator of 35’800 km, so this value has already been included in the calculation. The radius of the Earth is 6’370 km and has also been treated as a constant to simplify the calculation for antenna (satellite dish) pointing purposes.

If you have a negative elevation value, then that satellite is over the horizon and will not be visible to you.
You would also need to consider if the downlink footprint(s) cover your region.

Current Calculator

The Whyte current calculator below enables you to predict your DC group current requirements for Whyte IRS products. When designing your own system plans it is essential that current loading is not exceeded to ensure continual system performance. Whyte PSUs are already de-rated. Don’t forget to include the LNB/s and other devices (such as GTUs).
