The Com-Power 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
The preamplifier can be powered by its internal,
rechargeable 6 VDC NimH battery pack or the supplied
charger/power adapter. The front panel has indicators
for RF ON/OFF, power, battery low, amplifier saturation,
as well as charging status.
The matching network enclosure is secured to the
bottom side of the of a 60.5 cm square, polished
The AM-741 has a 1/4 inch x 20 threaded hole on the
bottom of the matching network enclosure, which is
used to secure the antenna to a tripod.
Com-Power?s AT-220 Tripod is the recommended
support for this antenna.

controller which can be used to monitor saturation
and battery low conditions. It also allows the user to
remotely enable/disable the RF measurement circuit.
