Electrical Symbols — VHF UHF SHF
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".
How to Create an Electrical Diagram Using VHF UHF SHF Library
- Open ConceptDraw DIAGRAM new document page.
- Select libraries from Electrical Engineering section.
-
There are a few different ways to place an object into your drawing:
- Click on an object and then click on the document, at the place you want the object to be inserted.
- Perform a drag-and-drop from the library to your document.
- Double click on an object’s icon in the library to place an object in the center of your document.
- Select the Smart Connector tool
. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
- Result: Electrical Diagram.

Multiprotocol Label Switching (MPLS). Computer and Network Examples →
Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunication networks that implements the data transfer from one network node to another using the labels. ConceptDraw DIAGRAM is a powerful network diagramming and vector drawing software that provides the Computer and Networks solution with wide set of ready-to-use predesigned vector stencils and examples to help you design the MPLS Networks quick and easy.
Interior Design. Plumbing — Design Elements →
Every interior design project starts from a deep understanding of all the utilities used in the building. In the first place, plumbing projection stage is crucial for the future design because it is very important to fit all the elements in their places correctly. Kitchen interior, for instance, will depend on the plumbing very much. Planning the layout of bathroom facilities, plumbing and sanitary equipment is a critical stage of the interior design of the entire house. Suppose, you do not need to see grill in your bathroom and the toilet in your kitchen, you need to give the proper consideration to the plumbing and piping planning. The ConceptDraw Plumbing and Piping Plans solution delivers the kit of 4 vector libraries containing more than 120 elements as pumps, tanks, pipes, boilers and other bathroom equipment for depicting Plumbing & Piping Plans. Using the Plumbing library, enables designing plumbing and piping interior designs, schemes and blueprints of water supply and sewerage systems.

Mesh Network Topology Diagram →
The reliability is a cornerstone for any corporate computer network. If you want to provide a high fault tolerance, a mesh network topology would be the solution. The main advantage of this network is that every node can work as a commutator, although it’s not easy to set up this kind of network. A mesh network topology may be full, or partial. Full mesh network means that each node of the network (computer, workstation or other equipment) is connected directly to each of the other nodes. A partial mesh topology means that a part of nodes are connected with a whole network, and the other part of nodes are only connected to those equipment, they exchange the majority of data. This illustration shows schematic diagram of a partial mesh network containing six nodes. Each node is represented as a circles and connections are drawn as straight lines. The connections may be both wired and wireless. This scheme can be used to make the specific logical or physical network diagrams by means the ConceptDraw Computer and Networks solution.
Flow chart Example. Warehouse Flowchart →
If you want to find a way to understand complex things in minutes, you should try to visualize data. One of the most useful tool for this is creating a flowchart, which is a diagram representing stages of some process in sequential order. There are so many possible uses of flowcharts and you can find tons of flow charts examples and predesigned templates on the Internet. Warehouse flowchart is often used for describing workflow and business process mapping. Using your imagination, you can simplify your job or daily routine with flowcharts. Warehouse flowcharts are used to document product and information flow between sources of supply and consumers. The flowchart provides the staged guidance on how to manage each aspect of warehousing and describes such aspects as receiving of supplies; control of quality; shipment and storage and corresponding document flow. Warehouse flowchart, being actual is a good source of information. It indicates the stepwise way to complete the warehouse and inventory management process flow. Also it can be very useful for an inventory and audit procedures.
