Hearing Impaired Tramsitter Antenna Location

[dhunsaker6]

We recently upgraded our transmitter and are getting a lot of static with the Assisted Listening system. We would like to upgrade the antenna also but have not been able to find its location anywhere in the building. Our FM group is looking for the building plans. Does anyone know where the antenna is traditionally located in the chapel?

Usually the transmitter is in the sound rack, and the antenna has something like 25-50' of cable or so. Find the transmitter and follow the wire. In the case of my stake center, it's in an area above the sound rack where the organ speakers are.

It does beg the question why things got worse after the transmitter was changed. Probably a bad connection somewhere or they accidently pulled the antenna down trying to connect it.

It varies from building to building and installer on where the antenna might be located. How old is your building? Where is the sound cabinet located?

Listen Tech 50 ohm impedance.
Comtech and Williams are 75 ohm impedance.

Feed line and antenna should be changed out as part of transmitter swap if going to Listen TX.

These are very low power systems and you need to preserve as much gain and efficiency in your system as possible.

Also our antenna is mounted to wall in center of the furnace room over the overflow.

Dave- that would sound like a late 60s thru 1970s stevens design building with the mech room above the overflow. I have worked in a few of those buildings, found 1 or 2 that had the sound cabinet up there as well, and a few that at one time had the sound cabinet up there but the cabinet was later relocated down to the main floor in a room.
