The LA Tv transmissions get a little weaker at 50 feet , are a little stronger at 25 feet and the optimum height is 12 to 15 feet. About 2 NM(dBm) better at 12 to 15 feet then 25 feet. And from 25 to 50 feet about 2 NM(dBm) weaker. So lower is better , but even so it's not that much. I recommend a Winegard HD7698P antenna with and without a CPA-19 preamp. Connected to one Tv , no splitters in the coax line from the antenna to the tv , as a test of reception. If testing reception without the preamp , all of the preamp needs to be disconnected , the outside part and the inside part , the coax will go from the antenna to the tv and thats it , with no preamp.
