A.H. Systems Model SAS-551 Passive Monopole Antenna SPECIFICATIONS GENERAL DESCRIPTION The A.H. Systems passive monopole antenna is a general-purpose transmitting antenna which cover the 10 KHz – 40 MHz frequency range. Each unit comes with a telescoping rod and ground plane. Review this manual and become familiar with all safety markings and instructions. -
Page 6: Operating Instructions
A.H. Systems Model SAS-551 Passive Monopole Antenna OPERATING INSTRUCTIONS ASSEMBLY INSTRUCTIONS To prepare the antenna for operation, attach the telescoping rod antenna element to the top of the ground plane box. Connect the rod antenna by pushing straight down on the female connector on top of the amplifier. - Page 7 50 ohm match. This requirement is typical for antennas with short radiators (radiator length of λ/10 or less) and that operate below 30 MHz. The SAS-551 antenna by itself does not represent a 50-ohm load to the signal source. OPTIONAL EQUIPMENT...

ANSI C63.5:2017 and CISPR 16-1-6:2017. Our telescoping rod with a BNC connector that is supplied with the SAS-551 has an average radius of 2.223mm. The formula for calculating the capacitance is (per ANSI C63.5:2017 and CISPR 16-1-6:2017): Eq 1 = (55.6 h) / (ln(h / a) –... - Page 11 A.H. Systems Model SAS-551 Passive Monopole Antenna Active Monopole Calibration The antenna factor for the rod antenna shall be determined by measuring the signal transfer characteristics with the matching device and assuming that the antenna is a short monopole with an infinite ground plane.
