Wireless transmission trough walls
« on: October 24, 2013, 07:16:05 pm »

Looking at a Shure BLX24 or 24R system for an install.  It specs as 300' line of sight.  I want to rack it in the audio closet.  I only need to transmit 100' (absolute max), but there will be a block wall between (7' from the receiver if it makes a difference).   Any hope?

Thanks

No guarantees.

Mount the antennas on the outside of the wall for line of sight. Can you drill a hole through the wall to run cables through?

To replace $20 worth of wire will require at least $1000 of RF if you want reliability.

Drill the damn hole and be done with this silliness.

Tim, I'm feeling obtuse.  Are you saying I can extend the antenna through the wall for $20?  Who offers such a wire?

Thanks

You can get ready made cables from a local supplier. Look in the owners manual. It's usually 75ohm cable with BNC connectors. Not too long....shorter the better.

I believe he was saying to drill the hole and run a wire as opposed to any RF solution.

Am I to understand that by wire you mean a wired mic?  The client wants a wireless mic to avoid dragging a cable thru patrons over a 75' use area.

David, your use of the word 'client' implies that someone is paying you to do this.  However, the questions you are asking imply that you aren't qualified to do this...

No, we are talking about mounting the antennas in a different location so they will be line of sight with the transmitter (mic) and running antenna wire to the antennas, leaving the receiver in the closet.
