With the change over to digital television broadcasting, high definition broadcasts are now the standard in the majority of markets.Most households can now receive free HDTV signals with the right antenna, a set-top box and/or a high-definition television.
This antenna is designed to pick up UHF frequencies. It may pick up VHF in certain markets.
Due to the earth’s curve, a TV Antenna is only capable of receiving signal up to 70 air miles, in optimum conditions. Any TV Antenna that claims up to 150 miles is most likely false advertisement.

Is this a digital antenna? Analog
and digital signals are broadcast on VHF and UHF frequencies, so all antennas
can pick up digital signals. Its more a matter of getting an antenna that
covers the frequencies that your stations are broadcast on (VHF/UHF). This is a
bit confusing when manufacturers list an antenna as "Digital Ready",
or "HD Antenna", but whether they are labeled this way or not, all
antennas have this ability.
How much signal will I
lose if I put this in my attic? You will lose 40-50% of your
signal strength when placing an antenna in an attic that is covered by plywood
and asphalt shingles. Even more signal is lost with foil covered insulation,
metal roofs and concrete structures. Beyond a range of 30-35 miles an attic
installation is generally not recommended. Because of the high signal loss of
an attic installation, an antenna with twice the range is needed to receive the
same amount of signal. Digital reception has a much higher threshold of signal
strength than analog reception.
Do I need a
rotator? It depends on how wide a direction your antenna
covers. This feature is called the beam width. The average antenna has a beam
width of 35 degrees, out of 360. Go to a site like www.tvfool.com or www.antennaweb.org and look at the compass
orientation. If the difference in degrees between all your desired stations is
great than your antennas beam width, then you will need a rotator. Keep in mind
that larger antennas that have a boom length over 131 inches need a rotator
that can withstand the windload and torque we suggest the CM9521.
What is the difference between a directional,
multidirectional and omnidirectional antenna? Directional
antennas pick up from a narrow direction usually around 40 degrees wide out of
360 and is best for long range reception. Multidirectional antennas have a wide
beam width usually 60-90 degrees, allowing them to receive stations that are
coming from multiple directions. Omnidirectional antennas receive signal from
all directions, and have the shortest range.
