This higher power also translates into smaller receiving dishes and points out a generalization between a satellite's transmission and a dish's size. As the power increases, the size of an antenna's dish will decrease.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup><sup class="noprint Inline-Template" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citing_sources" title="Wikipedia:Citing sources"><span title="This citation requires a reference to the specific page or range of pages in which the material appears. (July 2016)">page needed</span></a></i>]</sup> This is because the purpose of the dish element of the antenna is to collect the incident waves over an area and focus them all onto the antenna's actual receiving element, mounted in front of the dish (and pointed back towards its face); if the waves are more intense, fewer of them need to be collected to achieve the same intensity at the receiving element. </p><p>A major attraction of the band over lower frequency microwave bands is that the shorter wavelengths allow sufficient angular resolution to separate the signals of different communication satellites to be achieved with smaller terrestrial <a href="/wiki/Parabolic_antenna" title="Parabolic antenna">parabolic antennas</a>. From the <a href="/wiki/Angular_resolution#The_Rayleigh_criterion" title="Angular resolution">Rayleigh criterion</a>, the diameter of a parabolic dish required to create a radiation pattern with a given angular <a href="/wiki/FWHM" class="mw-redirect" title="FWHM">beamwidth</a> (<a href="/wiki/Antenna_gain" class="mw-redirect" title="Antenna gain">gain</a>) is proportional to the <a href="/wiki/Wavelength" title="Wavelength">wavelength</a>, and thus inversely proportional to the frequency. At 12 GHz a 1-meter dish is capable of focusing on one satellite while sufficiently rejecting the signal from another satellite only 2 degrees away. This is important because satellites in FSS (Fixed Satellite Service) service (11.7-12.2 GHz in the U.S.) are only 2 degrees apart. At 4 GHz (C-band) a 3-meter dish is required to achieve this narrow angular resolution. Note the inverse linear correlation between dish size and frequency. For K<sub>u</sub> satellites in DBS (Direct Broadcast Satellite) service (12.2-12.7 GHz in the U.S.) dishes much smaller than 1-meter can be used because those satellites are spaced 9 degrees apart. As power levels on both C and K<sub>u</sub> band satellites have increased over the years, dish beam-width has become much more critical than gain. </p><p>The K<sub>u</sub> band also offers a user more flexibility. A smaller dish size and a K<sub>u</sub> band system's freedom from terrestrial operations simplifies finding a suitable dish site. For the end users K<sub>u</sub> band is generally cheaper and enables smaller antennas (both because of the higher frequency and a more focused beam).<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> K<sub>u</sub> band is also less vulnerable to rain fade than the K<sub>a</sub> band frequency spectrum. </p> <div class="mw-heading mw-heading2"><h2 id="Disadvantages">Disadvantages</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ku_band&action=edit&section=8" title="Edit section: Disadvantages"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>There are, however, some disadvantages of the K<sub>u</sub> band system.

Therefore, the K<sub>u</sub> band satellites typically require considerably more power to transmit than the C-band satellites. </p><p>Another weather-caused degradation called "snow fade" is not specific to the K<sub>u</sub> band. It is due to snow or ice accumulation on a dish significantly altering its focal point. </p><p>The satellite operator's Earth station antenna requires more accurate position control when operating at K<sub>u</sub> band due to its much narrower beam focus compared to C band for a dish of a given size. Position feedback accuracies are higher and the antenna may require a closed loop control system to maintain position under wind loading of the dish surface. </p> <div class="mw-heading mw-heading2"><h2 id="See_also">See also</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ku_band&action=edit&section=9" title="Edit section: See also"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Multifunction_Advanced_Data_Link" title="Multifunction Advanced Data Link">Multifunction Advanced Data Link</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ku_band&action=edit&section=10" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text"><a rel="nofollow" class="external text" href="https://ieeexplore.ieee.org/document/1160089/;jsessionid=0A8FCFADFCE36B3BA0A6FB54F88A2849?tp=&isnumber=26011&arnumber=1160089&punumber=8332">IEEE Std 521 - 2002</a> URL only available to IEEE members</span> </li> <li id="cite_note-2"><span class="mw-cite-backlink"><b><a href="#cite_ref-2">^</a></b></span> <span class="reference-text">Note that in the band 11.2–12 GHz the <i>working</i> definitions of K<sub>u</sub> band and <a href="/wiki/X_band" title="X band">X band</a> overlap;
