SWR (Standing Wave Ratio) - in RF engineering and microwave, the ratio of the amplitude of the maximum (in a line) to the amplitude of the minimum (in the same line) of the standing wave in a cable, antenna or waveguide. SWR is a rate of the impedance matching of the load with the internal impedance of the feeder line or waveguide. The problem with mismatched impedance leads to the appearance of unwanted standing waves along the transmission line.

SWR is defined as the ratio of the amplitude of the standing wave (unwanted) in the maximum to the amplitude at the minimum along the transmission line. SWR characterizes the degree of matching of the loading Wi-Fi antenna and the feeder (coaxial cable or feeding waveguide). Sometimes SWR is given for matching the output of the wireless Wi-Fi Access point and it’s feeder.

In practice, there always exists some part of the transmitted energy that is reflected and returned back to the transmitter. Too much reflected energy degrades the operation of the wireless transmitter or can even damage it.

According to the US Department of Labor, poor hiring decisions cost companies 30% of their first year's earnings. For a software development manager, this means knowing what good habits you want your team culture to be proactive before interviewing candidates.

In addition to creating effective recruiting methods, it is also very important to establish a team-oriented work culture and encourage mutual cooperation.

What is the most important factor to consider when building a good software development team?

Building a great software team starts with having effective hiring methods. Hiring the professional people at the right time to get the right opportunities can nurture people, build teams and bring success to the company.

On June 10, 2019, the US Marine Forces has finally awarded Sikorsky Aircraft company with a contract worth of $542 million to make the production of six brand new VH-92A helicopters. New aircrafts will be the part of US presidential helicopter air fleet. Sikorsky Aircraft will supply spare parts and supporting equipment for the helicopters.

The new VH-92A helicopter will eventually replace the VH-3D and VH-60N that have been on duty by military forces for more than forty years before today. The new design of the aircrafts not only increases the possible payload, but also improves maintainability, availability and electronic communications. At the time of preparation for production, the flight test time of the VH-92A exceeded 520 hours, including the operation on the South Lawn of the White House in September 2018. The 92A is based on the S-92 aircraft. As of April 2019, the aircraft had accumulated more than 1.5 million hours of flight, with an average of 14,600 hours per month.
