Active Monopole Antenna, 9 kHz to 30 MHz

(1 customer review)


The AM-741R is an Active Monopole Antenna operating over the frequency range of 9 kHz to 30 MHz (usable up to 60 MHz). Its removeable, telescoping rod element is adjustable from 23 to 105 cm (approximately). Most standards specify a rod height of 104 cm (41 inches). Due to the high impedance of the rod element, a matching network with a high input impedance and 50Ω output impedance (for connection to the measurement equipment) is needed. The AM-741R provides this and also incorporates a low-noise preamplifier, thereby increasing the sensitivity and signal to noise ratio of the measurement system.

  • Frequency Range: 9 kHz to 30 MHz (useable up to 60 MHz)
