A good antenna for general area coverage that features a doughnut pattern and extends horizontal distance in a 360-degree radius is a dipole antenna. Dipole antennas are typically used for omnidirectional coverage, providing consistent signal strength in all horizontal directions while minimizing vertical range. Another option is the omnidirectional vertical antenna, which also offers similar coverage characteristics. These antennas are commonly used in applications like broadcasting and wireless communication.

Does shape of the antenna effect the magnetic field?

Yes for instance a dipole will have a doughnut shape field and a directional like a yagie will have a long teardrop shape field at the front end and a shorter teardrop field at the rear and some smaler fields sideways and a parabolic disc wil have a very long teardrop shape field


What is the suspension design of a 1962 mini cooper?

I believe the early coopers are the same as all mini's and that is dry suspension there is a solid rubber ring and that's the total suspension . I think the suspension works with a type of swing arm attached to the wheel hub and the other end located by a socket into the rubber ring (or doughnut) as it was known hope this helps


What are the Circular singly linked list applications in real life?

best example is trains...where each coach is connected to next coach except the engine and the last coach..when we need to add a coach we need to move to the right position and adjust the connecting point suitably!!


How DM plant are design?

Since there is continuous withdrawal of steam and continuous return of condensate to the boiler, losses due to blowdown and leakages have to be made up to maintain a desired water level in the boiler steam drum. For this, continuous make-up water is added to the boiler water system. Impurities in the raw water input to the plant generally consist of calcium and magnesium salts which impart hardness to the water. Hardness in the make-up water to the boiler will form deposits on the tube water surfaces which will lead to overheating and failure of the tubes. Thus, the salts have to be removed from the water, and that is done by a water demineralising treatment plant (DM). A DM plant generally consists of cation, anion, and mixed bed exchangers. Any ions in the final water from this process consist essentially of hydrogen ions and hydroxide ions, which recombine to form pure water. Very pure DM water becomes highly corrosive once it absorbs oxygen from the atmosphere because of its very high affinity for oxygen. The capacity of the DM plant is dictated by the type and quantity of salts in the raw water input. However, some storage is essential as the DM plant may be down for maintenance. For this purpose, a storage tank is installed from which DM water is continuously withdrawn for boiler make-up. The storage tank for DM water is made from materials not affected by corrosive water, such as PVC. The piping and valves are generally of stainless steel. Sometimes, a steam blanketing arrangement or stainless steel doughnut float is provided on top of the water in the tank to avoid contact with air. DM water make-up is generally added at the steam space of the surface condenser (i.e., the vacuum side). This arrangement not only sprays the water but also DM water gets deaerated, with the dissolved gases being removed by an air ejector attached to the condenser.
