What is an LNB?
The LNB (Low-Noise Block downconverter) is the small device mounted at the focal point of your satellite dish. It receives the satellite signal, amplifies it, and converts it to a lower frequency that travels through your coaxial cable to the receiver.
LNB Types Explained
Universal Ku-band LNB (Most Common)
This is what 90% of MENA satellite viewers use. It has two local oscillators:
- LOF 1: 9,750 MHz — for the low band (10,700–11,700 MHz)
- LOF 2: 10,600 MHz — for the high band (11,700–12,750 MHz)
The receiver switches between bands using a 22 kHz tone signal. A Universal LNB works with Nilesat, Arabsat, Hotbird, Turksat, and virtually all Ku-band MENA satellites.
Single-Band Ku LNB
Uses only one LO (typically 9,750 MHz). Cheaper but can only receive the low band. Not recommended unless you only need a few specific transponders.
C-band LNB
Uses LOF: 5,150 MHz. Needed for C-band satellites (3,400–4,200 MHz) which require large 1.8–3m dishes. Rarely used for consumer TV in MENA but common for professional feeds and in Africa/Asia.
Ka-band LNB
For the newer Ka-band (18–22 GHz). Not commonly used for TV; more for satellite internet services.
How to Choose
For MENA satellite TV, get a Universal Ku-band LNB. Done. It works with all major satellites (Nilesat, Arabsat, Hotbird, Turksat, Es’hail, Yahsat).

Dual, Quad, and Octo LNBs
- Single — one output, one receiver
- Twin/Dual — two outputs, two receivers
- Quad — four outputs
- Octo — eight outputs
For multiple receivers or TVs, choose accordingly. Each output is independent.
