Antenna, Wideband Discone

EM-6115 | 10 kHz – 2 GHz

The EM-6115 is a broad band collinear array allowing very wide Omni-Directional frequency coverage in a single package. Below approximately 100 MHz, the EM-6115 acts as an active vertical rod which offers 10 to 12 dB Greater unsaturated instantaneous dynamic range than competitive antennas (overload field strength: 2 V/meter) which greatly reduces intermodulation generated signals in a typical read world RF environment. In the congested spectrum above 100 MHz the antenna is passive and contributes no intermodulation products so the overload point is determined solely by the receiving instrument. This immunity to overload can often make the difference between useful signal output and an indecipherable jumble of spurious products and is accomplished without compromising sensitivity. The antenna collapses for convenient storage and transport.
