Hello,

I am interested to see if anyone else has noticed cell phone interference on UHF wireless mics in thier installations? Since we switched to UHF from VHF, we noticed that if the speaker has his cell phone on, it will interfere with the wireless mic he is using. Thanks!

I haved used dozens of Shure wireless without any issues, except when 2 units were on the same channel and in different rooms.

Mic check one, two... lol

Strongly urge going to variable frequency wireless mics. If you have a problem, rescan and find a new frequency. If you suspect a problem ahead of time, pick up the cell phone, call the movie theater info line, and scan the frequency for the mic.

Shure has this option available for very reasonable rates....

Is it a Nextel phone? I have noticed that the Nextels work on a frequency that many speakers pickup on. Maybe it is that. It does a tap, tap, tap noise.
Just my opinion, I could be wrong.

Not all wireless microphone systems are created equal. Start off first witha "ture diversity" system. This has two antennas on slightly diffent frequencies always sampoling the signal. if one drops out, the other picks it up seamlessly. And yes, selectable frequencies are amust for any situation. Other things to consider are bui8ld quality, and of course " battery management" Most major touring musical acts have a person that does nothing else other than babysitting the wireless microphones and managing the batteries.
