This final blog post in our “Back to Basics” series addresses the Return Loss and Voltage Standing Wave Ratio (VSWR) characteristics of antennas. It relies on obsolete military specification MIL-C-17. Return loss = -20 * log(Γ) For example, if the VSWR value is 3 : 1, we will first have to find the reflection coefficient's value using it, Γ = 0. It is a ratio. Gain Var5. From the beginning until the present, he invested a total of $50,000 into the project, and his total profits to date sum up to $70,000. In this situation, 10% of the incident power is reflected back to the source while the balance of 90% is transmitted forward. Assuming the simplest case where system 1 is a cable with nominally zero loss (cannot be exactly zero with a non-zero reflection), then the reflection loss of the whole system will be somewhere between -8dB (when the reflections add in phase) and -14dB (when they add out of phase). Cash on Cash – The return on investment. This tool provides an estimate of the Return Loss of a cascade of two RF subsystems. It also estimates a percentage of current balance required to get to the breakeven point again. * A negative value (below zero. Insertion loss is almost universally expressed in decibels (dB), and is generally supposed to be a positive number but we forgive you in advance if you ever say "this attenuator has -9. Consider the antenna being used in transmit mode.
