Mag.Loop Stealth 6.6-29.7 MHz with ATU 2
The Stealth Loop by Ciro Mazzoni was designed to provide an effective antenna to users with limited space. One goal was to build an antenna which is not instantly recognizable as an antenna. The Stealth Loop covers a frequency range from 6.6 to 29.8 MHz (45 to 10m), the maximum power is 125 W CW. Compared to an ideally mounted fullsize dipole the antenna has about 4 dB less signal gain on 40m, and about 0.3dB less on 10m. The useable bandwith which can be used without retuning is about 5 kHz on 40m, and 25 kHz on 10m. Usually an SWR of 1.3:1 or better is achieved.
The directional pattern of the loop is slightly directional at very low elevation angles, and depending on the frequency. At hugher elevation angles the pattern becomes nearly round and without nulls. Overall the pattern is also influence by the position and ground conductivity below the antenna. The loop should be operated only outdoors, not inside a building. The minimum clearance to any solid structures should be around 2m to the sides and above the antenna. Solid structures are walls, roofs, railings etc. The placement of the Stealth is very flexible: you can put it on the floor as well as on the roof of a car, on a balcony or garden desk, everything goes as long as the minimum sideways/top clearance of 2m is achieved.
