I don't fully understand your question. Are you looking for an AP with separate 2.4 and 5Ghz connectors? If so, we have the AP-228 (RP-SMA) or the AP-274 (N connectors). In either case, you would have to use only the primary chain connector of each AP, configure the AP to run in single-chain mode, and the accomodate the following caveats in the config:
* disable ARM and set static channel plan
* you lose all MIMO capabilities and rates and your AP effectively runs on legacy rates
* no heatmapping or RTLS in airwave
