It is often suggested to a T.V. viewer in the fringe area that incorporation of a Booster Amplifier in his receiving installation would give rise to significant improvement in the quality of reception. An analysis of the performance of the Booster Amplifier has been made with simplifying assumptions. The analysis shows that the Booster does very little improvement in reception so far as V.H.F. channels are concerned. Limited tests carried out so far confirm this. The Booster, however, may have better utility in U.H.F. channels principally due to the much lower antenna temperatures. In all cases an improvement is feasible where this device is installed right on the antenna.
