ZWR-400 is a band crossover with four inputs: FM, VHF, UHF1 and UHF2 and one output. The device is used to sum signals from VHF and UHF TV antennas and a radio antenna. FM frequency response: 87.5-108 MHz, VHF: 174-240 MHz, UHF1 and 2: 470-694 MHz.
The ZWR-400 provides supply voltage transfer from the input to VHF and UHF outputs, enabling power to antenna preamplifiers. In the case of
active antennas the power supply will be automatically transferred to the appropriate inputs. When the passive antenna is connected, the voltage transfer will be
blocked for the port to which it is connected.
The crossover can be mounted on the 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 UHF inputs allows the use of passive antennas operating in a wider range of UHF frequencies. There is no need for additional filters or crossovers.
The UHF2 port (with higher pass-through attenuation) is dedicated to antennas receiving stronger signals (additional illumination, transmitter with higher power). Thanks to such a home installation, we can control signals of different power 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.
