The circulator/filter method is used with virtually every 2+0 or more indoor radio setup. Combiners are used for outdoor models such as those we have been discussing here and a typical loss per side is about 3.6 dB or 7.2 dB on the path. This shouldn’t be overlooked when designing high capacity / high modulation systems since you will need every bit of system gain you can get (or antenna sizes must be greatly increased).
Whenever looking at competing radios and their published capacities, it is also important to closely examine and compare their system gains to see what works on your proposed path. As an example, the Navigator High Capacity 80 MHz Bmw radio has a 68.7 dB system gain at 4096 QAM vs. 77 dB system gain on the Aviat WTM 4100 similarly configured.
