Do cell phone jammers meant to block CDMA GSM 3G signals also stop UHF and VHF signals
You can use cell phone jammer in church and your mic would be ok. You see, GSM/CDMA/3G signals have a frequency of 800-900MHz, 1800-1900MHz and 2100-2200MHz (last one is 3G). VHF band uses 300-300MHz, and UHF band is a wide band with 300-3000MHz frequencies but as a rule microphones are not using high frequencies for their work. UHF/VHF jammer blocks only the most used parts of those bands - 140-180MHz from VHF and 450-480MHz from UHF.
As you can see, all you need to do is to make sure you have low-frequency microphone that would not be jammed by your cell phone jammer. And if someday you would need to jam both mobile phones and low-frequency band, you still can do it - just visit the source link and read more about it.
