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.
