EMCO Conical Log Spiral RF Radio Antenna ETS-Lindgren
EMCO / ETS-Lindgren 3101 Conical Log Spiral, 200 MHz - 1 GHz
The EMCO / ETS-Lindgren 3101 conical log spiral antenna was designed by the Department of Defense for MIL-STD-461E measurements. The original drawings provide the basis for th Model 3101.
Once used exclusively for MIL-STD and SAE testing, conical log spiral antennas are effective for other types of measurements too. For example they can be used for close-in "quick-looks" to find the spectral characteristics of RF emissions. For immunity testing, conical log spirals generate reasonable field strengths with modest power input. By placing conical log spiral antennas in a vertical position with respect to the ground plane, they can also be used as omni-directional, horizontally polarized antennas for electromagnetic site surveys.
The 3101 Conical Log Spiral is made with spiral windings of coaxial cable attached to the outside of a fiberglass cone. Outside windings improve heat dissipation. This cone is attached to a delrin rod equipped with an aluminum base. The antenna mount base accepts standard 1/4 in x 20 threads from a tripod.
