Miteq AR-2-70 75 ohm Line Amplifier – we have a quantity of four of these 1 watt amplifiers two are for 70 MHz and two are 140 MHz.
If you have a long 75 ohm cable run at 70/140 MHz there will be losses with each foot. At our teleport we limited cable length to 100 feet, but used one of these amplifiers for a run in excess. These amplifiers to boost the signal by up to 1 Watt.
Here is some wordage from the Miteq datasheet:
This independent dual-channel IF line driver amplifier system is designed to compensate for long IF cable run losses in terrestrial or satellite system applications. Available at 70 MHz or 140 MHz center frequencies, the amplifiers are designed either for 50 ohm or for 75 ohm cables. The amplifiers are gain matched with low noise figure and high dynamic range. The amplifiers
are powered with two independent power supplies.
