Celwave has not existed as Celwave since the early to mid 1980's when it became part of RFS hence the lack of available info via an internet search.
NOTE: These if i recall correctly were typically in the 8 - 16DB range gain.

Thanks. I knew that they no longer existed as Celwave. Perhaps someone on here will have an old brochure or paper documentation lying around (or a good memory).

I mostly want to know what the rated dB gain is.

I have some experience with the 800Mhz version of that. This style preamp was typically used to overcome
a receive system total insertion loss's and were aligned such that the total receive gain was only slightly to
overcome the total insertion loss. To do that you have to open up the unit and make adjustments while
using a tracking generator on the input vs the ouput.
