To add to what Chuck said - The manufacturers don’t make the antenna’s specific to the various manufacturers other than adding an adapter plate. You can remove the radio mount from a Andrew / Commscope antenna and replace it with the adapter kit for the radio brand. The adapter kits can be ordered individually as needed - the hard part is finding the part numbers. Radiowaves is the same. We have changed a number of antenna’s from Dragonwave, PTP800, and SAF to PTP820 or SAF over the years.
If anyone wants Andrew Remec (PTP800) adapters we have a pile of them.
