- Not currently - look at the Sabine and Sacom products.Isn't there is a sticky on 900mhz devices needing licenses?
- Modern technology requires that we keep upping our game. Study-up.I have dabbled with the Shure frequency planning software but it's over my head.
- Be sure that they do a frequency coordination for all the RF devices on the whole campus, not just the Gym - otherwise it is futile (or as the techno-borg say: "Impedance is futile").Whenever they redo the gym sound system they will have a contractor do all of it professionally.
The referenced post is inaccurate. Pro audio wireless equipment operates in the 902 - 928 MHz band, not the STL band. The 902 - 928 MHz band is not restricted.
No references because this is common knowledge among RF engineers. The antennas are not tuned and matched to 50 ohms, and neither are the receiver inputs, therefore the cable doesn't matter. Impedance matching is critical for transmitters because it affects power transfer and heat dissipation. Receivers only care about signal voltage, not power.
Agreed, there is some special equipment that is sold only for use by broadcasters (Shure X1 band products and Nady makes a version of their UHF4, there may be others), and it is possible, but highly unlikely, that us mere mortals would come across it. The point I was trying to make is that the Original Post (not the one you read today) about not using anything in the 900MHz band (which has since been modified to clarify they meant 944-960 MHz) was overly broad and inadvertently discredited legitimate products that can be useful when trying to get enough open frequencies to use for a production. - Thanks to Webmaster Dave that got this corrected to reduce confusion by the readers.Sorry, but you are wrong. The author of the sticky knows his stuff. There was or maybe still is some equipment made for the Part 74 948-952 band. Only licensed radio and TV stations may use that spectrum. Speaking as one of those broadcasters, I would be hopping mad if I had interference from an illegal user, and wouldn't hesitate to involve the FCC. Granted, the equipment for Part 74 seems to be rare, and stuff for the 902-928 band is much more common.
