Active Receiving Antenna URA 30 - 500
This active monopole antenna is used as receiving antenna with omnidirectional characteristic.
It covers the frequency range from 30 - 500 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 unfavorable 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. An additional filter will be switched automatically if the field strength of unwanted signals exceeds a preset limit value.
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.
With regard to the robust construction and the use of weatherproof materials our active antennas can be used under extreme environmental conditions
