You may find that the central ridge/flair ideally needs to extend further to prevent 2.3 cutoff/dispersion and smooth out the impedance change

There is no reason why you cant start by taking one of Kents WA5VJBs flaired pcb vivalidis such as https://www.ebay.co.uk/itm/254170352417  (the hard bit) and then enclose it in a DIY horn surround built from metal or blank fr4 PCB to direct the radiation better
