SpletAntenna G1 at Hörby shortwave station, which was operated by Radio Sweden but was shut down in 2011. It consisted of 16 horizontal wire dipoles in a 4×4 array, suspended in front of a wire screen. Each of the 4 columns of dipoles is fed by a separate open-wire transmission line, which can be seen exiting at an angle from the center of each column. SpletThe construction design of the orange antenna frame allows full usage of the whip antenna for checking SW parallels of MW-DX stations, although if you chose to glue the antenna frame flush with the front of the back cabinet surface to simplify the gluing process, you may need to sand the whip antenna slot post slightly to allow free movement of ...

Due to different antennas and operating frequencies, the impedance presented by the antennas can vary greatly. The impedance mismatch caused in this way will cause great loss to the signal transmission, and even cause the transceiver to … SpletActive 3-30 MHz Hula-Loop Antenna for Shortwave. In the past, designs that incorporated an amplifier in the antenna were called "antennafiers" so perhaps this is a "loopifier". The differential amplifier solves matching issues and the varactor tuning gives excellent out-of-band rejection for even cheap receivers. preliminary and general in nz
