You can get 2 buck deer tags, It was something I was interested in also. I got this from the WY Game and Fish Website regulations on deer.
"For deer, no person shall apply for and receive more than one (1) full price deer license through the initial drawing. After the initial drawing is completed, any person may apply for and receive up to two (2) full priced deer licenses
provided that at least one (1) license is a Limited Quota Type 3 any white-tailed deer license valid for Hunt Areas
10-16, 18, 22-24, 26, 34, 51, 55, 57, 59, 60, 62-66, 74-81, 88, 138-140, 142, 143 or 161. However, no person shall
apply for and receive more than a total of two (2) deer licenses valid for the taking of antlered or any deer, of
which not more than one (1) shall be valid for antlered or any mule deer."
As for Antelope I don't have an answer. Hope this helps
