[QUOTE="Brian jojade, post: 141868, member: 211"] Re: Going to buy wireless IEM system 600mhz devices will be legal to operate for at least the next 4 years, but since we know they are going away, if you can purchase in a lower band, it would be advisable to do so. Some things to consider with your bandwidth selection. The lower the frequency, the easier to penetrate objects. Old VHF systems could more easily broadcast through walls and such. The issue was that the band was so congested, it was easier to move up to the UHF bands to find free channels. Moving up to the 2.4ghz and 5ghz bands creates even more difficulties in penetrating objects. Higher frequencies require a stronger transmitter to get the same range. This can result in shorter battery life of a transmitter. Luckily technology has evolved significantly that addresses these issues. On the downside of lower frequencies, is antenna size. Looking at a 1/2 wave antenna, in the 2.4ghz is about 2.5 inches. A 1/2 wave VHF antenna at 174mhz would be nearly 34 inches. Pretty unpractical for a mobile application. [/QUOTE]
