No-Mask Combiner
This configuration refer to a Combiner which makes use of Bandpass No-Mask Filters (3 and 4-Pole) while Mask Filters are built-in the Transmitters.

Though not allowing Adjacent-Channel combination, this approach can be adopted with existing Transmitters already having their own built-in filters:

• Suitable to adapt to existing site configurations
• Adjacent-Channel combination not possible
