2.6 Antenna Installation
The AR6201-(X0X) requires a standard 50 Ohm vertically polarized VHF
antenna. Follow the antenna manufacturer's installation instructions. In
addition consider the following recommendations:
• The COM antenna shall be on an electrical conductive surface or, on a
ground plane with sufficient area of approximately 60 x 60 cm
installed.
(VSWR ≤ 3:1)
• The COM antenna should be as much as possible separated from GPS
antennas installed (not less than 50 cm)
• The COM antenna should be as far as possible separated from ELT
antenna installed.
Some ELTs have exhibited re-radiation problems generating harmonics
that may interference with other receivers. This can happen when the
AR6201 is transmitting on certain frequencies such as 121.5 MHz or
121.175 MHz, which may cause the ELT output circuit to auto-
oscillate.
2.7 Location of internal Circuit Breaker
The internal Circuit Breaker is resettable by means of a matching
nonconductive tool (may be self-made).
