“RF channels” are not the TV channels we normally think of, but are the broadcast channels (i.e., allocations of spectrum) used by stations.Įach station in your surrounding area will be assigned a single RF channel that you can look up in your signal report on. This antenna is designed to pick up high VHF (RF channels 7-13) as well as UHF (RF channels 14-51). The company claims this transformer allows 98% of the available broadcast signal to reach the cable with minimal attenuation possibly resulting from impedance mismatches on the antenna. It also comes with a 75-Ohm transformer (Balun) to reduce impedance along the antenna to the coaxial cable. The beam angle is 43 degrees for the UHF frequency spectrum (470 – 700 MHz). The antenna gain of the ClearStream 4 is 12.25 dBi - or decibels relative to isotropic radiator, which as a consumer you can consider as plain old decibels. Some good cable I recommend is Mediabridge Coaxial Cable. I recommend RG6-type cable, making sure it’s of the tri- or quad-shielded variety to protect against electromagnetic interference. You’ll need to purchase a 75-Ohm coaxial cable to connect the antenna to your TV. A metal roof or radiant barrier (the latter especially if installing it in the attic) Gain and AmplificationĪs is typical of long-range antennas of its kind, this antenna isn’t amplified so doesn’t come with a built-in preamplifier.Local electromagnetic interference (e.g., nearby streetlights, electrical interference from household appliances in homes with older electrical wiring, etc.).Trees, landscape topographical features, etc., which are in the line-of-sight path to the towers.Keep in mind however that the range you’ll get may differ from this figure - depending on signal strength at your your location.Įxamples of some local variables that affect signal reception include: The antenna picks up TV signals from up to 70 miles away. With its black mesh reflectors and distinctive looped dipoles, the ClearStream 4V focuses antenna receptive power for increased range and minimized signal multipath interference.Īctually, this unit is comprised of two combined ClearStream 2V antennas that are stacked together for wider reception.
