The device is used to sum signals from VHF and UHF TV antennas and a radio antenna. FM frequency range: 87.5-108 MHz, VHF: 174-240 MHz, UHF1 and 2: 470-694 MHz. ZWR-400 provides power supply voltage transfer from the input to the VHF and UHF outputs, enabling the power supply of antenna preamplifiers. In the case of active antennas, the power supply will be automatically transferred to the appropriate inputs. After connecting a passive antenna, the voltage transfer will be blocked for the port to which it is connected. The crossover can be mounted on an antenna mast, thanks to a special, splash-proof ABS housing. The crossover is a professional solution with built-in SAW filter technology. Thanks to this, GSM/LTE and 5G signals will not penetrate the installation. The use of filters at the UHF inputs allows the use of passive antennas operating in a wider range of UHF frequencies. There is no need to use additional filters or crossovers. The UHF2 port (with higher insertion loss) is dedicated to antennas receiving stronger signals (fill light, transmitter with higher power). Thanks to such a home installation, we can control signals of various powers without additional attenuators or selectively tuned amplifiers. The solution is dedicated to SMATV applications for single-family houses. For larger installations, we recommend using WWK series channel amplifiers.
