Your card will only be charged once item ships.
The AKG AB 4000 is an in-line antenna signal amplifier that is used to compensate for the signal loss from cable attenuation in large antenna networks. The amplifier comes with an ultra-linear RF amplifier circuit that offers up to 17 dB of amplification and can be remotely powered by the PS 4000 or by an ASU 4000 Antenna Power Supply Unit. Each AB 4000 can be used with up to 150 ft. (46 m) of RG 58 and up to 300 ft. (92 m) of RG 213 cable.
With amplified antennas and 2 AB 4000s the total cable length can be up to 485 ft. (150 m) with RG 58 and up to 950 ft. (292 m) with RG 213. The AB 4000 comes with a 3 bit input attenuator for compensation of the connected cable length. The antenna booster also is equipped with 2 BNC connectors and 1 power indicator LED. The splitter comes in a waterproof metal housing and therefore is even suitable for use outdoors.
