When a sine wave starts out at the input of the antenna (the feedpoint), it has one polarity. When it hits the end of the antenna 1/4 of a cycle later, it is reflected back in the opposite polarity and makes it back to the feedpoint another 1/4 of a cycle later. Since that ...
of antenna for an application is 1/4 (one-quarter) the wavelength of the target frequency. This is referred to as the "resonant length" of an antenna for a specific frequency. When a sine wave starts out at the input of the antenna (the feedpoint), it has one polarity. When it hits...
Sinegubko documented a wave of incidents that involved attackers obtaining administrator (root) access to Web servers and installing rogue Apache modules during August and September 2012. The purpose of the modules was to inject rogue iframes into legitimate websites hosted on those servers. This ...

in the opposite polarity and makes it back to the feedpoint another 1/4 of a cycle later. Since that reflected wave in the opposite polarity makes it back to the feedpoint 1/2 of a cycle later, it now matches the polarity of the 2nd half of the cycle of the original sine wave is...
