Im guessing you mean using the airmax bullet as the wan input. The issues you would encounter are 1. be aware that the later wifi ac std bullet (best speed) only works with another AC bullet or airmax ACproduct as the AP, unlike the older m series bullet version which can be client to almost any wifi any AP / router. So if your source source of wifi isnt AC airmax too not going to work with bullet on your mast. The Poynting or other antena/cases for the rutx11 may be your best choice. .2 The bullet, whichever version , requires a 24v poe injector to send power to it up the mast via ethernet cable. The typical poe injector has ac 115v-240v adaptor not12vdc so you would need to run an inverter suffering 5-10% energy loss as waste heat in conversion or use a special boost converter type poe injector which is 12v in 24v poe out.
