RJ Communications made these, a small Phoenix company (of the three companies that made ferrite circulators in Phoenix: RJ, Celwave and EMR, RJ is the most obscure, and I believe they are no longer in business. The RJ design is identical to Celwave circulators. The one pictured is a non-tunable dual section design and it will likely fall off considerably in performance in the 440MHz range. Some will say you can mess with them and re-bias the magnets to move the freq but I would recommend finding the right part that was intended to be used at the freq range it was intended for because a dual section circulator used out of band will have considerable losses.
