Antennas more complex than the dipole or vertical designs are usually intended to increase the directivity and consequently the gain of the antenna. This can be accomplished in many different ways leading to a plethora of antenna designs. The vast majority of designs are fed with a balanced line (unlike a monopole antenna) and are based on the dipole antenna with additional components (or elements) which increase its directionality. Antenna "gain" in this instance describes the concentration of radiated power into a particular solid angle of space, as opposed to the spherically uniform radiation of the ideal radiator. The increased power in the desired direction is at the expense of that in the undesired directions. Power is conserved, and there is no net power increase over that delivered from the power source (the transmitter.)
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Gain when referring to an antenna refers to what about radiated power?
Ah, so.. concentration

Beyonce and husband Jay Z are friends with President Barack Obama and First Lady Michelle Obama. She performed "America the Beautiful" at the 2009 presidential inauguration, as well as "At Last" during the first inaugural dance at the Neighborhood Ball two days later. Beyonce and Jay Z held a fundraiser at the latter's 40/40 Club in Manhattan for Obama's 2012 presidential campaign which raised $4 million. Beyonce uploaded pictures of her paper ballot on Tumblr, confirming she had voted in support for the Democratic Party and to encourage others to do so. She also performed the American national anthem at his second inauguration, singing along with a pre-recorded track. She publicly endorsed same sex marriage on March 26, 2013, after the Supreme Court debate on California's Proposition 8. In July 2013, Beyonce and Jay-Z attended a rally in response to the acquittal of George Zimmerman for the shooting of Trayvon Martin.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Beyonce sang which song during the 2009 presidential inauguration?
Ah, so.. America the Beautiful

Humans would also have derived enormous benefit from the dogs associated with their camps. For instance, dogs would have improved sanitation by cleaning up food scraps. Dogs may have provided warmth, as referred to in the Australian Aboriginal expression "three dog night" (an exceptionally cold night), and they would have alerted the camp to the presence of predators or strangers, using their acute hearing to provide an early warning.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did a dog's good hearing help humans with?
Ah, so..
early warning.
