Active Monopole Antenna 0.01 - 30 MHz

Vertically Polarized Omnidirectional Antenna Characteristic


This active monopole antenna is used as receiving antenna with omnidirectional characteristic within the long-, medium- and short-wave bands.

It covers the frequency range from 0.01 - 30 MHz.

Due to its small dimension and the very low radiation coupling, this active antenna is particularly qualified for mobile as well as stationary application under unfavourable localities.

An amplifier circuit directly connected to the base point of the antenna rod matches the high impedance of the rod to the low input impedance of the receiver or the connected coaxial cable.

Our active receiving antennas are fitted with amplifiers providing a high RF dynamic range in order to avoid degradation of the reception-system characteristics.

A multistage protection circuit at the input of the active element ensures that the antenna electronics will not be damaged even in case of lightning strikes in close proximity.

The effective height (the ratio of the output voltage over the field strength) is constant over a wide frequency range. This also makes this active antenna ideal for performing field strength measurements.

Since the length of the antenna rod should be selected that the intrinsic noise of the amplifier is just covered by the external noise the optimal rod length is different for each frequency band.

A rod length of 100 cm is a fair compromise for the frequency band from 10 kHz to 30 MHz.

Screw-on rods allow easy matching of the rod length to a wide variety of operating conditions.

With regard to the robust construction and the use of weatherproof materials our active antennas can be used under extreme environmental conditions.

The operating voltage for the antenna is 39 Vdc. The AAN power supply series or an AAS Antenna Distribution System is used to feed the operating voltage to the active element via the coaxial cable.
