Despite family doubts that a woman can work on electronics, I saved my mom money by putting in a cable splitter myself. Having previously worked for a cable company, I knew it was very important to invest in a high end, three-way CATV splitter. The cable outlet supported the modem for her telephone, so I knew the signal would be strong enough to support both her phone and TV.
Her cable company’s minimum trip charge was $75 to come out and ‘upgrade’. By installing a $17 splitter, I was able to get her basic cable on the kitchen TV with no effect on her call quality.
