## Questions & Answers

**Q: How far away can the freq source be?**
A: It's dependent on source output power.  I mainly use it for verifying ENG wireless microphones during press check-ins.  Don't typically get a reading until under 20" away from the TX source.

**Q: Does it come with both the vhf and uhf antena?**
A: This unit comes with (1)one 5" universal antenna that seems to cover the vhf/uhf frequencies very well, it even works well down to 72 MHz (model aircraft radio) not so much at 2.4gHz range.

**Q: Could I use this to find out Hz vibration plate vibrating at?**
A: This item only picks up RF frequencies. Vibration plate is an audio wave form I believe? You would need a sound wave sensor to see the frequency such as a Accelerometer. This is a sensor that measures the dynamic acceleration analyzer of a physical device as a voltage & frequency.

**Q: Will this count cell phone frequencies (i.e. 4G)?**
A: No it does not
