Com-Power AM-741 Active Monopole Antenna, 9 kHz - 30 MHz

The Com-Power AM-741 Active Monopole Antenna, 9 kHz - 60 MHz was designed to measure electric field strength in the frequency range from 9 kHz to 30 MHz. This antenna includes a built-in broadband amplifier covering the frequency range of operation. The built in preamplifier improves the sensitivity of the antenna and also provides a 50 Ω matched output.

The antenna amplifier is enclosed in an aluminum enclosure. The 41 inch collapsible rod element is connected to BNC connector located on the top the amplifier enclosure. The amplifier enclosure is mounted on the bottom of a 60 x 60 cm stainless steel plate. The front panel of the AM-741 Monopole antenna has battery status and saturation indicators. The saturation indicator will illuminate if the if the field measured is saturating the built in preamplifier.

The antenna can be used for 6-8 hours continious with a fully charged battery. An external charger addapter is included with each antenna.

The antenna has 1/4 inch x 20 threaded hole which allows the AM-741 to be mounted on an antenna tripod with matching threads. The manual and certificate of calibration will be shipped with each unit.
