Why is the neper a useful unit for transmission line calculations?

SWR Measured at the Transmitter versus SWR at the Antenna says the neper is "a more convenient unit for transmission line calculations". Why exactly? What is a neper, and what about it makes it more convenient than the more common decibel? Are there…

What is dB(μV/m), and what are its applications?

Many radio coverage tools yield results in dB(μV/m). For example, CRC-COVWEB or nearly any tool based on the Longly-Rice model. The unit occurs in regulations sometimes as well. For example, maximum permissible exposure limits may be given in V/m,…

Getting the wrong answer from percentage power/transmit power calculation

I have the following example taken from the "ARRL General Class Manual", 7th Ed, 4-4. Here's a practical application. Suppose you are using an antenna feed line that has a signal loss of 1dB. You can calculate the amount of transmitter power that's…
