St. NW Washington, DC 20554 ATTN: Carl Huie Dear Mr. Huie: In Cooperation with the FAA, development of the Transponder Landing System (TLS) by ANPC is close to completion. The TLS is soon to receive type certification and Hillenbrand Industries airport owners will be preparing the FCC Form 406 for site license. Due to integration procedures into the National Air Space, the TLS has not received full FAA Certification necessary for the FCC form 406 to become active at this location. We would like to request an STA for a 180 day duration to allow for final integration into the National Air Space. This STA would similar to the previously filed STA file # 4912—EX—PL—95 Call Sign KA2XEU. It would be our understanding that the STA would be superseded by the Operator License when approved. The Following is a summary of the frequency use request: Location of Station Batesville, IN NL 39° 20‘ 56.41" WL 85° 15° 27.79" Runway heading 36 Frequency Power (EIRP, dBm) Emission Designator Signal Name 108.35 32 6KO0A9W Localizer 333.95 40 300HA 1N Glide Slope 1030.0 60 6MOOMID Interrogation 1090.0 20 6GMOOMID AOA Calibration Runway heading 18 Frequency Power (EIRP, dBm) Emission Designator Signal Name XXX.XX(assigned ILS freq.) 32 6KOOA9W Localizer YYY.YY(assigned ILS freq.) 40 300HAIN Glide Slope 1030.0 60 6MOOMID Interrogation 1090.0 20 6MOOMID AOA Calibration Attached are copies of the antenna patterns.

Transponder Landing System Transportable Transponder Landing System Advanced Navigation & Positioning Corporation SIGNAL STRENGTH LINK BUDGET

Signal Strength Link Budget 1. GTU The minimum field strength on the glide path and within the localizer course sector must not be less than —107 dBW/m*. The following link budget verifies the design parameters that meet this requirement. For the Localizer transmission: Given: e Localizer transmit antenna gain of +7dBi on bore—site to +3dBi @ 35° off bore—site — as shown in figure 1. e Transmit power is 24 dBm (.25 watt) The field strength (Fs) in dBW/mis given by equation 1, Fs = 1010g(10°*"°>4pI+*7? Eq. 1 Where... G,, = transmit antenna gain r= 18nm p = transmit power ... yields a predicted field strength of —102 dBW/m*. Frea Space . 680 388‘ .'J. o 90°® P270° io. MB Tsl d es sade " Figure 1.

Signal Strength Link Budget For the glide slope transmission: Given: e Antenna gain of +7dBi on bore—site to +4dBi @ 35° off bore—site as shown in figure 2. * Transmit power of 34 dBm (2 watts) With r= 10 nm, eql yields a glide slope field strength of —89 dBW/m*. smsmms h—P|anQe mew— E—P{and Figure 2.

Signal Strength Link Budget 2. Interrogator For the interrogation signal strength, the horizontal and vertical antenna patterns are shown in figures 3 and 4 respectively and have a gain of 12 dBi. At 35° off bore—site the gain is +8 dBi. Given that the peak transmit power is 56 dBm (400 watt), Eq 1 yields a field strength of —66 dBW/m* which will meet the requirement for interrogation signal greater than or equal to —86 dBW/m*.
