Hi Tim. If you are meaning that you want to use a F300-16 as an AP, and connect the other 300-16’s as SM’s to that… then unfortunately Cambium decided to remove that feature.
As Jacob said, the ePMP 1000 & 2000 series (and ePMP1000 connectorized, Force 180, Force 190, Force 200 SM’s) all had the ability for any device to act as an AP or as an SM. We also used to use that feature lots for farms (connecting a small network of 3 or 4 radios - house, barn, Quonset, cameras, gate) and that was one of the often advertised features of the ePMP line. But when they came out with the 3rd generation gear, Cambium decided to remove that feature. So now, you’d need to step way up to the ePMP 3000 line to get point-to-multi-point AP capabilities now.
There are rumors that Cambium is going to now add that feature back in as yet another one of their licensing schemes, so that you may be able to purchase that feature back at some point… but I don’t know. I can’t see paying them extra for a feature they removed, which we used to have built in.
Anyway, so if you are looking for that, you’ll either need to buy a 3000 Series AP and Antenna (which is total overkill) or you’ll unfortunately need to go to another brand. We hadn’t purchased anything other than Cambium for many years until they did this to us - but there’s really no other sensible choice.
