URMA2000 Series Broadband Amplifiers

Urma2000 is a new family of amplifiers with a high output level. They are designed to compensate for attenuation in the distribution cable network with high channel loading. The amplifiers have built-in electronic slope and level adjustments with the ability to control both locally and remotely. The high output level allows to reduce the amount of active equipment in the network which increases its reliability.
