Is it possible to place 2 different antennas (selected from your catalogue) for different application and frequency range (for instance: BLE antenna and ISM 868MHz antenna), and connected to one only 50ohm coax cable? I have to design and place a combiner (mix) before the antennas and coax cable, and a demix after coax cable.
For sure I will get more insertion loss by this solution, but my question is this: is it possible or not? Which other issues could happen? Please take into account that the two signal in different frequency range will be filtered enough in order to avoid interferences.
