Which wireless system is the best depends on what you are going to use it for. Musicians and performers that experience problems with interference can find satisfaction with a UHF wireless system, while a VHF system that doesn't require such expensive gear suffices if there is little interference.

A wireless system in this sense, is something that transmits sound on a radio wavelength to a speaker or other piece of broadcasting equipment. The systems are useful for speaking, singing, playing instruments or otherwise requiring amplification of the source. Disposing of the cables reduces the many things that can happen like getting tangled or tripping over them.

A main issue is whether to buy a system that is UHF or VHF or even digital. Since UHF systems are more likely to be more expensive, there is a notion that they are superior. Although this may be the case, it certainly is not always born-out.

Chances are UHF systems will encounter fewer drop-outs, but their battery life is more limited than a VHF system's. Parts for UHF systems are typically more expensive as well as the original purchase itself. If you are experiencing interference in using your gear, UHF is probably the best choice. In simpler circumstances it won't be neccesary.

Whether buying a UHF or VHF-based system, having frequency agility is a must if you are serious about mitigating interference. In many areas, both UHF and VHF frequencies are widely used, and you will need the ability to adjust until you find one that is not. Frequency-agile systems are available at differing levels-- an acceptably agile one might be adequate for some uses, but one with a wide range of frequencies will very useful in other circumstances.

Another possibility is the rather new digital systems. These require less power and are seldom dealing with interference, and are not that expensive now. Because the receiver doesn't have to guess at what the signal received was supposed to sound like, transmissions are less likely to be degraded when sent via digital information. Although calling Digital UHF or VHF is often done, those definitions are usually used to define the analog systems while digitals are combined together under one label.

Antennae diversity is a feature that is important and not that expensive anymore. The meaning of this is that the system looks for the best and strongest signal and oscillates between the choices. It prevents your sound from being disrupted if the strength of the signal is inadequate. Relatively cheap and common now, true-diversity systems have two antennae.

Digital microphones might be the best choice for the price , and are comparable to quality UHF systems in many instances. Paying a lot, however may not be necessary as VHF systems can do well in instances where there is no interference. Think about the battery life of the transmitter if that's a consideration.

We hope that this short piece will help in making a choice of systems, whether it's digital, UHF, or VHF..
