The device is used to sum signals from VHF and UHF TV antennas, as well as radio antennas. Passband for FM: 87.5-108 MHz, VHF: 174-240 MHz, UHF1 and 2: 470-694 MHz.ZWR-400 allows transferring the supply voltage from the input to the VHF and UHF outputs, enabling powering antenna preamplifiers. In the case of active antennas, the power supply will be automatically transferred to the respective inputs. When connecting a passive antenna, the transfer of voltage will be blocked for the port to which it is connected. The switch can be mounted on the antenna mast thanks to a special, waterproof ABS enclosure.The switch is a professional solution with built-in SAW filter technology. This prevents GSM/LTE and 5G signals from penetrating the installation.The use of filters on the UHF inputs allows using passive antennas operating in a wider range of UHF frequencies. No additional filters or switches are required.The UHF2 port (with higher insertion loss) is dedicated to antennas receiving stronger signals (lighting, higher power transmitter). With such a home installation, we can control signals of varying power without additional attenuators or selectively tuned amplifiers. This solution is tailored for SMATV applications for single-family homes. For larger installations, we recommend using channel amplifiers from the WWK series.
