What to consider when choosing the right LNB for your satellite system

When you’re shopping for an LNB, below are some of the few things you need to consider.

1. Signal gain

In a satellite system, the gain of the LNB needs to be as high as possible. This is because you want to receive a strong signal from your satellite receiver. The higher the gain, the better your chances are of receiving a strong signal.

2. Phase Noise

The phase noise of an LNB is important as well. Phase noise refers to how much interference is introduced by the LNB into the signal it receives from its feed. The lower the phase noise, the better your signal will be able to travel through long cable runs and into your receiver.

3. Noise Figure (NF)

The NF of an LNB reflects how much energy is lost in unwanted signals compared with wanted signals. A good NF should be less than 0.5 – this means that 90% of the signal will come out without any noise at all, while 10% would still sound like music if played on speakers instead of satellite equipment.

4. Desense Level

Desense level is the amount of power required by your dish antenna to get an image on your TV. The higher the desense level, the better the signal quality. Desense levels in the order of -50 dBm indicate very good filters.

5. Temperature Range

The temperature range for an LNB can vary from -40 degrees Celsius to +60 degrees Celsius. This is important because if you live in an area where it gets very hot or cold, you may want to choose an LNB that has a wide temperature range so that you don’t have any issues with performance during those times of the year.

6. Voltage Standing Wave Ratio (VSWR)

VSWR indicates how many waves are generated by the antenna as it scans across the sky. The lower this number is, the more efficient the antenna will be in transmitting signals from satellites over long distances without losing too much power due to reflection and loss from obstructions.
