As of 2015 a variety of murals from internationally recognized street artists have appeared throughout the city as a result of the efforts of Art Whino and RVA Magazine with The Richmond Mural Project and the RVA Street Art Festival. Artists who have produced work in the city as a result of these festivals include ROA, Pixel Pancho, Gaia, Aryz, Alexis Diaz, Ever Siempre, Jaz, 2501, Natalia Rak, Pose MSK, Vizie, Jeff Soto, Mark Jenkins, Etam Cru- and local artists Hamilton Glass, Nils Westergard, and El Kamino. Both festivals are expected to continue this year with artists such as Ron English slated to produce work.

The Homestead Act of 1862 provided free land to settlers who could claim and "prove-up" 160 acres (0.65 km2) of federal land in the midwest and western United States. Montana did not see a large influx of immigrants from this act because 160 acres was usually insufficient to support a family in the arid territory. The first homestead claim under the act in Montana was made by David Carpenter near Helena in 1868. The first claim by a woman was made near Warm Springs Creek by Miss Gwenllian Evans, the daughter of Deer Lodge Montana Pioneer, Morgan Evans. By 1880, there were farms in the more verdant valleys of central and western Montana, but few on the eastern plains.
What year did the Homestead Act provide land to settlers?
1862

Although a resonant antenna has a purely resistive feed-point impedance at a particular frequency, many (if not most) applications require using an antenna over a range of frequencies. An antenna's bandwidth specifies the range of frequencies over which its performance does not suffer due to a poor impedance match. Also in the case of a Yagi-Uda array, the use of the antenna very far away from its design frequency reduces the antenna's directivity, thus reducing the usable bandwidth regardless of impedance matching.
What term can be used to refer to the usable spectrum of an antennas frequency?
bandwidth
