A log-periodic aerial antenna 28-1 Logo is a modern broadband antenna with double polarization, is designed to receive digital terrestrial television DVB-T/T2 in the UHF (470 ... 790 MHz) and is a copy of the passive digital antenna Logo 28-2 but with the addition of the amplifier. Characteristic features of the antenna include the ease of installation (antenna is fully assembled), the flatness of gain characteristics throughout the band of VHF and UHF and the impedance match of 75 Ohms, so the antenna does not require the balun device. The antenna cable is connected to the F connector (included). The price of external antenna Logo 28-1 very attractive and even if you count the retail value of the materials from which made the cost of antenna outdoor antenna Logo 28-1 will be higher selling price.
The antenna was developed by the specialists of the Scientific and technical University's electronics Department. The number of radiating elements and their shape was optimized via specialized software to provide the required operating parameters. The implementation of antenna with two operating bands has allowed to reduce the size of the antenna with respect to the classical broadband antenna solution.
The antenna is a typical urban or suburban antenna to receive the signal T2 in the full range of UHF frequencies in horizontal, vertical or mixed polarization. It can be installed on antenna mast on the roof or on the wall or balcony railing.
Emitting elements with a diameter of 3.92 mm was manufactured of tempered aluminum alloy. The longest element, while maintaining the elasticity, maintains a constant load located at the end corresponding to the weight less than 0.8 kg. For comparison, the weight of the dove does not exceed 0.4 kg.
Price external digital antenna Logo 28-1 includes everything needed to connect the antenna to the cable but does not include the cost of the power supplies or the injector. When buying an antenna for it pay attention!
