Deciding on the wrong 2-way radio to your restaurant, that may include choosing the improper frequency band, an unacceptable quantity of channels or insufficient electrical power might be like throwing money away. Due to the sizable investment involved, you and the employees could be expected to live with a two-way radio error for many years. Instead, make sure you pick the right radio to do the job. One of the worst moves is usually to obtain a VHF radio. The main difference between UHF and VHF could be explained with frequency penetration. VHF waves travel about twice the distance of UHF waves on open ground, rolling hills or through foliage. However, VHF waves are weak at penetrating walls, buildings and rugged terrain. So, in case you are working exclusively outdoors with open land, rolling hills or heavy trees, VHF radios work most effectively. In different other situation, including indoor to external use, UHF radios will be the choice. Choosing excessive power might be a waste of money to the upgrade, in addition to choosing a lot of channels. Any standard restaurant will have sufficient coverage having a 1-Watt UHF radio. Any wattage beyond that is not useful, if you do not want to set off site at the same time. In such cases, you may want to look into a 2 or 4 watt walkie talkie. The number of channels is very important at the same time. Make an effort to think 2-5 years ahead of time and take into account the most of channels you'll need. If all your employees can be on a single channel, whatever, then this 1 channel radio is right for you. If, nevertheless, you need multiple channels, make sure you receive the proper number. As an example, say you desired your automobile valets using one channel plus your wait-staff on another (other product need to communicated with each other). But, you since the manager desire to meet with both groups. Then, you will nee an invisible with a minimum of two channels. You will require no less than 4 channels when you have 4 teams of people speaking at the same time, same for 6, 10 etc. For details about bo dam dung cho nha hang see this popular web page. bo dam dung cho nha hang
