Is it possible to re-use the UA830A and UA830UB inline antenna amplifiers for new wireless microphone gear operating in the 470-698 MHz core TV broadcast band? What is the usable bandwidth of the UA830A and UA830UB inline antenna amplifiers?
Following is the operating bandwidth information for the UA830A and UA830UB inline antenna amplifiers:
|UA830A||Frequency - Low (MHz)||Frequency - High (MHz)|
|Measured 3 dB Bandwidth||781||818|
|Measured 10 dB Bandwidth||775||824|
|Measured 3 dB Bandwidth||692||722|
|Measured 10 dB Bandwidth||685||728|
The UA830A and UA830UB in-line antenna amplifiers feature bandpass filters with relatively sharp cutoffs. Consequently, they will need to be replaced with new wideband in-line amplifiers, model UA830USTV, when changing out "700 MHz band" wireless microphone equipment. The UA830A and UA830UB inline amplifiers will substantially attenuate any signals outside of their filter passbands.
