(or previous versions), that has been
installed to meet the requirements of the installation manual may be approved for use with the UC10x.
For specific technical requirements for the antenna can be found in TSO-C74d (RTCA/DO-181E §2.2.15) (UC100,
UC103) or TSO-C112e (RTCA/DO-144A §2.2.11) (UC101, UC102) or TSO-C66c (RTCA/DO-189 §2.2.17). The antenna
requirements contained in the TSO and associated MOPS are equivalent for all intents and purposes, and can be
used interchangeably. Table 19 provides a simplified summary of antenna requirements.

WARNING: It is the responsibility of the end user to know the regulatory requirements for
their application / use case. This is an oversimplified interpretation intended to facilitate
understanding of the antenna requirements. There are other antenna types that could meet
all requirements. There may also be antennas that fall within the description above that do
not meet all requirements. See regulations pertinent to your use case (MOPS, TSO, etc.) for
details and to make your own determination.

is the TSO for distance measuring equipment (DME), which uses the same frequency band, and thus the
same antenna, as transponders

Transponder MOPS do not explicitly state monopole, but extrapolating from the required minimum vertical
beamwidth (25°), horizontal beamwidth (360°), and ground plane size (4’ Ø), is an ideal monopole.
