When choosing between a pre-amplifier like the 7777 or a distribution amplifier the length of the run to the location of the distribution system must be taken into consideration. If that distance is less than 50 ft. you may be ok with the distribution amplifier. However I recomend the 7777 pre-amplifier as close to the antenna as possible. This amplifies the signal before the loss in the coax and will deliver enough signal to allow for splitting and distribution to four or even more TV sets and will provide better reception from weaker stations.
