Abstract:
1. An amplifier for use in a buoyant cable antenna operable to receive signals within a frequency band, said amplifier comprising: a first amplifier operable to provide amplified signals based on the received signals; a bandpass filter arranged to pass filtered signals within a first portion of the frequency band, the filtered signals being based on the amplified signals; an attenuator arranged in parallel with said bandpass filter and operable to attenuate signals within a second portion of the frequency band, the attenuated signals being based on the amplified signals; and a second amplifier operable to provide an amplified output including first amplified signals within the first portion of the frequency band and to provide second amplified signals within the second portion of the frequency band, wherein the first amplified signals have a first gain, wherein the second amplified signals have a second gain, and wherein the first gain is more than the second gain.
