A:AnswerFizz- It is always advisable to use a cable, as short as possible, to connect the antenna to the preamplifier. Weak signals can degrade as they go through cables and splitters. Also keep in mind, this CM-7777 preamp is designed for areas that do not have any strong local channels. Strong signals can overdrive the input to this amp and cause issues that resemble the symptoms of weak or poor quality signal. If you do have some strong signals in your area, then you might consider the Titan 2 CM-7778. That preamp is not as susceptible to being over-driven by strong signals.
