Based on your search for the Ubiquiti UBNT-PBE-M5-400 Powerbeam M5 25DBI 5GHZ Airmax Cpe 400MM, I see we have a few great options available around R2000. The Ubiquiti 5GHZ Airmax Powerbeam Cpe - 25DBI 400MM Dish for R2081 and Ubiquiti UB-PBE-M5-400 5GHZ 25DBI Powerbeam High-performance Airmax Cpe for R2312 both seem like excellent choices. Both are made by Ubiquiti and include the 25dBi antenna you asked about, but the second option describes itself as their high-performance model, so it may offer slightly better specs. With prices so close, it really comes down to reading the full details of each to see which better suits your specific needs. Please let me know if you need any other information to help you decide between these options.
