Philips Mant410 indoor antenna is perfect for increasing signals to VHF, UHF, FM and HDTV components, offering a piercing range of up to 25 miles through hilly terrain or tall buildings. Features 45db amplified tuning.

Parabolic antenna - The Parabolic antenna is a high-gain, reflector antenna used for radio, television and data communications, and also for radiolocation (RADAR), on the UHF and SHF frequencies. The relatively short wavelength of electromagnetic (radio) energy at these frequencies allows reasonably sized reflectors to exhibit the very desirable highly directional response for both receiving and transmitting.

KABC-TV - KABC-TV, "ABC7" is an American Broadcasting Company (Disney/ABC) owned station in the Los Angeles area, and is the West Coast flagship station of the ABC network. The station's transmitter and antenna located on Mount Wilson broadcasts the station's over the air analog television NTSC signal on channel 7 VHF and the digital television signal on channel 53 UHF (aka: KABC-TV DT or ABC7 DT) to the Los Angeles market.

Cage aerial - A Cage aerial is an antenna, which consists of several parallel running wires, which are radialsymmetrically arranged around a tower or a mast. An advantage of the cage aerials is the fact that the carrying tower or carrying mast can be grounded, which facilitates its use for other radio services, for example as carrier mast for the UHF/VHF.

Wavelengths maximum DBS the transmitting parabolic gives a ubiquitous feature of urban, suburban, and even rural, landscapes. In more complex designs, such as the Cassegrain antenna, a sub-reflector is used for radio, television and data communications on the UHF and SHF frequencies. Earlier applications included ground-based and airborne radar and radio astronomy. Extensive terrestrial microwave links between cellphone base stations and wireless WAN/LAN use have also proliferated this antenna type. A typical parabolic antenna has become a ubiquitous feature of urban, suburban, and even rural, landscapes.
