Language Translators in Separate Room

In our past Stake conferences we had the language translators on the stand off to one side. (Just one language, Spanish). We have received some comments that it’s loud and distracting for the first several rows in the chapel. I have been asked to look into moving the translators into a separate room. It’s easy enough to get them a monitor and sound but in my tests the additional walls prevent the signal from the transmitter to get very far into the chapel or the cultural hall without a lot of static, if it even is picked up at all. Has anyone had a similar issue they have overcome? I would like some kind of a mic and amplifier (if necessary) the translators can use and then run a cable into the chapel into the audio in RCA connector on the transmitter. I think a coax cable with RCA adapters would be a good shielded cable. The distance from the translators will be 30-40 feet. Thanks in advance.

We permanently installed a Williams Sound ANT 005 antenna, up on the ledge at the back of the chapel. We ran coax cable to a wall plate in another room, where we also have a connection to the building A/V distribution. For stake conference, we set up a interpreter station in the room, connecting the transmitter to the antenna connection and a TV to the A/V connection.

With the antenna installed where we have it, we've found the broadcast signal reaches much of the building. Listeners can sit anywhere in the chapel or cultural hall.

By the way, when we connect the transmitter to the above mentioned external antenna, we remove the "rubber duckie" antenna.

We run our Stake Conference cameras and sound from the Stake Clerks office because that is where the satellite/sound cabinet is. We pipe video and audio to an adjoining room, our Patriarchs office, and set up our live translation team in there. We take the translated audio signal back to the Clerks office, then send it on a "borrowed" coax cable in the ceiling into the chapel overflow room. In there we hang the small FM transmitter up on the wall. This puts nearly everyone in the chapel and cultural hall within a direct line of sight of the antenna. It all radiates pretty well to the rest of the building because it is in a fairly central location. Normally, the coax cable we use is part of the CCTV distribution, but we disconnect it from the CCTV splitter and use it for translation audio.
