Desktop 103 Antenna
The Model 103 antenna is designed for UHF/VHF reception within the 470-862 MHz frequency band. Its internal amplifier provides 28 dB gain with less than 2 dB noise figure. The housing is made from durable polycarbonate with an internal conductive coating. The antennas full extended length is 60 cm, retracting to 25 cm. It features 10 active elements with a dipole loop design for bipolar reception. Standard output impedance is 75 ohms via an F-type connector. The amplifier requires 5V DC power at 150 mA current consumption. It can receive DVB-T2/T digital signals with -96 dBm sensitivity. Built-in LTE filtering for the 790-862 MHz cellular interference band is included. Operating temperature ranges from -20 to +60 degrees Celsius. The antenna weighs only 180 grams without its base.
The structure includes a 360-degree swivel base with position-locking capability. Reception elements are constructed from gold-plated anodized aluminum. The circuit board uses SMT Surface Mount Technology for reduced noise. The included cable is a 1.8-meter RG-6 coaxial with copper shielding. A USB port draws power from a TVs USB port or an external adapter. The anti-interference circuit suppresses unwanted signals by up to 30 dB. Antenna gain is manually adjustable across three levels: Low, Medium,
