About;Kurtz-Under Band: The Kurtz-under band (Ku band) is a frequency range or segment of the radio spectrum from 11 to 17 GHz. This range is often used for satellite communications, including VSATs, and some types of satellite antennas.Linear regulators are less noisy than switch-mode converters, but also less efficient. A 6 V 200 mA LNB wastes 1.4 W at 13 V and 2.4 W at 18 V. Only very long, low cost steel core cables would need that much margin to compensate for voltage drop. In controlled conditions, a 9 V supply is often sufficient.
