Nady Systems Inc. manufactures wireless microphones and musical instrument systems in UHF and VHF formats. Differences of Nady UHF vs. VHF wireless systems are primarily situational -- with both types bearing pros and cons -- so users must evaluate current and future performance needs to determine the right type of Nady wireless system.
Wireless System Frequencies
Wireless mic and musical instrument systems emit broadcast radio signals through channel frequency bands set by the Federal Communications Commission. Very High Frequency wireless systems function within 150MHz to 216MHz band ranges, and Ultra High Fequency models function within 470MHz to 698MHz ranges. The wider UHF frequency range allows more wireless channel choices over VHF for flexibility and improved operation under less than ideal conditions. Wireless challenges include outside radio frequency interference and physical barriers that may infringe upon or inhibit the wireless device's operating frequency.
Nady UHF Wireless Facts
UHF wireless systems by Nady and other manufacturers are more expensive due to the inherent complexity and number of UHF frequency ranges. UHF systems offer an improvement through frequency absorbing or deflecting obstacles over VHF, employ more compact antennas and allow channel-switching capability for avoidance of competing radio devices on the same frequency.
Nady VHF Wireless Facts
VHF wireless systems are less costly than UHF systems, but offer less frequency channel ranges. VHF systems operate best when there are no obstacles between the source transmitter and wireless receiver, and employ manufacturer selected frequencies within VHF band ranges. Because of the relative simplicity of VHF wireless units compared with UHF, transmitter battery life and system noise reduction improve.
VHF vs. UHF Conclusion
The choice of Nady VHF vs. UHF wireless units hinges on venue type, desired system flexibility and cost. For wireless users performing in one or several locations known to be free of transmitter-to-receiver obstacles and limited outside radio interference, VHF systems are a logical and cost-effective choice. Traveling users who perform in many locations where physical obstructions, radio interference and optimum operating frequency bands are unknown will appreciate the benefits of UHF wireless systems.
