Don't know if it's still the case, but for a while some NHL arenas had low-power FM signals simulcasting the broadcasts since AM doesn't work well in that environment.
Also the case in major-junior, notably the OHL. About 15 years ago, when 88.7 myFM in Napanee had the radio rights to the Kingston Frontenacs, both home and away games, I was part of the tech team that installed a low-power transmitter inside what was then known as the Rogers K-Rock Centre, later the Leon's Centre and now Slush Puppie Place. We had a receive antenna on the roof of the rink, and attached to a platform in the rafters were an equipment cabinet, and a transmit antenna hanging down. In the cabinet were a fixed-frequency FM receiver tuned to 88.7, and a little Decade transmitter set to 90.1. There was no more than maybe half a second of delay on the broadcast, less when the commentators were using the newer Tieline IP codec and not the older Comrex POTS box.
