MEGAHERTZ SPECTRUM OBSERVED.  YOU CAN SEE THE 180 TO 186 MEGAHERTZ TV
CHANNEL AND THE REST OF THE TV CHANNELS FROM 470 TO 608 MEGAHERTZ.  THE
STRONG SIGNAL AT 162 MEGAHERTZ IS A NATIONAL OCEANIC AND ATMOSPHERIC
ADMINISTRATION WEATHER RADIO TRANSMITTER.  THE FM BROADCAST SIGNALS ARE
VISIBLE FROM 88 TO 108 MEGAHERTZ.  THERE IS A STRONG SIGNAL JUST ABOVE 600
MEGAHERTZ, AND THERE ARE SEVERAL MORE FROM ABOUT 750 TO 800 MEGAHERTZ.  SOME
OF THESE ARE PROBABLY 4G LTE OR 5G SIGNALS FROM THE AT&T CELL TOWER LOCATED
<  QST DE W1AW  =
A FEW BLOCKS AWAY AND DIRECTLY IN MY TV ANTENNAS MAIN PATTERN.  THERE ARE
OTHER STRONG SIGNALS FROM 700 TO 800 MEGAHERTZ.  MOST OF THE NON TV SIGNALS
ARE 10 TO 40 DB HIGHER THAN THE TV SIGNALS, BECAUSE THE ACTIVE SPLITTER
AMPLIFIES SIGNALS FROM 50 TO 1000 MEGAHERTZ, ALL OF THE NON TV SIGNALS ARE
AMPLIFIED ALONG WITH THE DESIRED TV SIGNALS.  THIS CAN CAUSE AMPLIFIER
OVERLOAD, TV FRONT END OVERLOAD, OR IMD PRODUCTS FALLING WITHIN THE TV
