File No. SES-LIC-20080910-01187
Dear Mr. Magallanes:
On September 10, 2008, CapRock Communications, Inc. (CapRock) filed the above-captioned 
application for a new license to operate a Conventional C-band1 fixed earth station.  CapRock 
proposes to use a 2.4 meter antenna.  For the reason detailed below, we dismiss the application as 
defective without prejudice to refiling.2
Section 25.112 of the Commission’s rules, 47 C.F.R. § 25.112, requires the Commission to 
return, as unacceptable for filing, any earth station application that is not substantially complete, 
contains internal inconsistencies, or does not substantially comply with the Commission’s rules.  
CapRock’s application is incomplete, which renders it unacceptable and subject to dismissal.  The 
deficiency is as follows:
In response to Question E15 of Schedule B, Caprock indicates that its antenna does not comply 
with the antenna performance standards in Sections 25.209(a) and (b) of the Commission’s rules, 
47 C.F.R. § 25.209(a) and (b).  Pursuant to Sections 25.132(b)(3) and 25.220(b) of the 
Commission’s rules, 47 C.F.R. §§ 25.132(b)(3) and 25.220(b), earth station applicants seeking to 
use non-compliant antennas must submit antenna radiation patterns in their applications.  
Although CapRock’s application included some patterns, it did not include the co-polarized 
antenna pattern in the elevation plane from 0 to 45 degrees, and in the azimuth plane from 0 to 
+/-7 degrees and 0 to +/- 180 degrees, and cross-polarized pattern in the vertical and horizontal 
plane from 0 to +/- 9 degrees.  Consequently, the application is incomplete and will be dismissed.
While we dismiss CapRock’s application on this basis, we take the opportunity to apprise 
CapRock of another question that arose when reviewing the application.  In response to item E48 
  
1 3700-4200 MHz and 5925-6425 MHz.
2 If CapRock refiles an application in which the deficiencies identified in this letter have been corrected 
but which is otherwise identical to the one dismissed, it need not pay an application fee.  See 47 C.F.R. §
1.1109(d).

of Schedule B, CapRock lists the maximum EIRP per carrier for proposed emission 1M15G7W 
as 19.07 dBW.  In response to item E49, CapRock lists the maximum EIRP density per carrier as 
43.65 dBW/4 kHz.  Using the proposed EIRP value of 19.07 dBW and a bandwidth of 1.15 
megahertz, we calculate the average EIRP density per carrier to be -5.51 dBW/4 kHz.  Because 
the maximum EIRP density listed in the application is 49.16 dB higher that the average EIRP 
density we calculate, we request Caprock to confirm the EIRP values prior to any refiling.
Accordingly, pursuant to Section 25.112(a)(1) of the Commission’s rules, 47 C.F.R. 
§25.112(a)(1), and Section 0.261 of the Commission’s rules on delegations of authority, 47 
C.F.R. §0.261, we dismiss CapRock’s application without prejudice to refiling. 
Sincerely,
