Cellular Phone Frequency Spectrum Usa Historical

Easy exchange - when I bought a USA Cellular Camera

With the crowded spectrum that we now deal with I have begun to add wireless systems in the lower frequency bands. This antenna lets me use my ULX-J1, QLX-D H50, and SLX-D G58 systems with the same antenna.

Well put together. Good sound balance across audible frequency spectrum. Comfortable over the ears for couple of hours, then with some periodic repositioning will add a few hours of comfort. I use it mainly with my home audio system that allows me to enjoy a rich sound without interfering with others in the house. Also good response when used with digital media (computer, tablets and phones) Yes I would buy it again and certainly recommend it to a friend.

The Era 300 produces sound unimaginable great frequency balanced across the spectrum and with Dolby atmos !! Welcome to the new Era of Sonos !

I got this today and it works great with my cell phone, it even came with a 3.5mm to 3.5 mm cable for cellular use...I was surprised..also do yourself a favor..install the gain jumpers as stated in the directions..it will give you more audio on a noisy day. HTH

I had some serious issues getting this working and turns out it’s best if you turn off your cellular service on your phone while doing the setup. Worked like a charm for me on multiple devices. A new update also improved integration with Apple HomeKit. Very happy with it now.

I have a cellular phone based app that I use for my intercom. So I use these so my camera ops in the field can clamp them to the camera tripods and put the phone right in front of them. They work awesome. Highly recommend and will be buying more.

I use this interface to send our church service audio over a conference line via cellular phone. Transmission is crystal clear!! Conference callers have been impressed by the clarity of the audio. Recommended product. 100% Satisfied. Would purchase again.

This thing never needs charging with the solar panel, and gets great cellular reception where our phone barely get any. Highly recommended this device

This microphone has great audio as long as the phone is in airplane mode. If it is not, any communication over the cellular antennas causes the ticking and distortion other reviewers have mentioned. When in airplane mode though, the audio is clean. I prefer to shoot video in airplane mode anyway so my recordings are not bothered by text messages or phone calls. So, this is no big deal for me. I love the mic and the build quality.
