Additional Information |
The first in a series of compact, highly efficient antenna designed and optimized for 2009 digital TV frequenciesClearStream antennas represent a new breakthrough in size and unmatched ultra efficient design and gain. Advanced design software allows these antennas to be smaller and powerful across the entire DTV spectrum offering consistent high gain. Advancements in antenna efficiency allows up to 98% of the available broadcast signal to actually reach the incoming antenna cable rather than being lost to impedance mismatches.
The patented ClearStream4 Tapered Loop design receives UHF channels and higher level VHF frequencies with a range of about 50 miles. They are engineered for extra strength and durability, using anodized aluminum for corrosion resistance and are easy to assemble. The ClearStream2 delivers TV signals from widely located (spaced) broadcast towers. The C4 offers flexible aiming characteristics with an extremely wide 70 degree beamwidth, while still providing resistance to multi-path interference.
The ClearStream4 delivers digitally perfect multiple station signals. With the efficiency of the C4 you can have range and power normally found in antennas up to 5 times the size in a compact and attractive form Channel 14 (471.25 MHz) Channel 33 (579.25 MHz) Channel 51 (699.25 MHz)
Frequently Asked Questions
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.
