Due to Rogue One being set close in time to Episode IV,
we see the original Red Five die at the battle of Scarif leaving the call sign available for Luke.
But, was Wedge Antilles part of Red Squadron at this point? If so, would he logically have taken part in the battle? We know there are survivors such as Red and Gold leader.
I can understand the actor not wanting to reprise his role, but was the character technically present?
I don't think Wedge is involved in the battle.
Reason for saying so was that in ANH, Wedge (Red 2) can be heard saying "look at the size of that thing", suggesting that being the first time he saw the Death Star.

It's not known if he was part of Red Squadron yet, but Pablo Hidalgo, a continuity and story development executive with the Lucasfilm Story Group, confirmed on Twitter that he wasn't involved in the battle:
@ShannonGCarter Were Wedge, Biggs, John D, Porkins, Theron Nett, Tiree and Pops at Scarif in Rogue One?
@pablohidalgo Wedge definitely wasn't. Biggs, doubtful. The rest, probably, in that we didn't reassign their call numbers.
As I mentioned in a comment on the question, David Ankrum, the original voice actor for Wedge1 had a brief voice cameo, as revealed in an interview with sound designer Matthew Wood:
Following his tendency to use the same handful of actors for the vocal roles, Wood has brought original 1977 "Star Wars" actors on board to use their voices for "Rogue One," such as Angus MacInnes and David Ankrum, who played Gold Leader and Red Two in "A New Hope."
Ankrum himself revealed on Twitter that he could be heard over the public address system at Yavin base:
@RenderedAddison I am listening for your voice. What scene is it in?
@DavidAnkrum1 PA Announcer on Yavin. Redirecting the pilots to Scarif!
Whether or not Ankrum's voice is meant to be Wedge is, as far as I know, unknown; Ankrum himself claims as much in his Twitter biography, but it hasn't been confirmed by more official sources as far as I know.
1 Random Star Wars trivia time: Wedge was portrayed in body by two actors: Colin Higgins (in the briefing scene) and Denis Lawson (in the Death Star battle itself), but both actors' lines were overdubbed by David Ankrum
Wedge was not in the battle but I assume he would have been part of the rebel alliance at that time. He was just elsewhere.
The Captain Antilles they page in the hanger was likely the Captain Antilles 3PO refers to in A New Hope. He was 3PO's master and Captain of the Tantive IV.
Apparently, yes. The IMDB trivia page for the movie says "A call for a Captain Antilles can be heard as the rebels prepare for their assault on Scariff."
