MFJ Small, high efficiency Loop Tuners
Click here to read Phil Salas review of the MFJ-936B, MFJ-935B, and MFJ-933.
Drape a wire around a bookcase or window and attach both ends to this new MFJ Small Loop Tuner. It instantly turns into a small, high efficiency multi-band transmitting loop antenna! You can operate 3.5 to 30 MHz with a full 150 Watts. No ground, radials or counterpoises needed.
The excellent performance of a high-efficiency small loop antenna is legendary and well proven by users all over the world. You'll radiate a low angle DX signal that literally rivals full size dipoles and work incredible DX!
It's a very quiet receiving antenna; you'll hardly notice static crashes. Its high-Q reduces QRM, overloading, harmonics. It's perfect for apartments, antenna restricted areas and portable operation.
A 13 foot wire formed into a loop operates 30-20 Meters (4 foot for 17-10 M; 7 foot for 20-15 M; 28 foot for 60-40 M). You can tune any shape loop; circle, square, rectangle, any odd shape. A quarter wavelength wire shaped as a circle is the most efficient.
A given wire length covers about 1.5 to 1 frequency range (i.e. 7-10 / 18-28 MHz, etc.). Exact frequency coverage depends on wire length, loop shape, surroundings and height above ground. Has MFJ low loss Butterfly loop tuning capacitor, no rotating contacts. Easy-Carry handle. Mount for PVC Cross on cover.
See June, 1986, QST or recent ARRL Antenna Handbook for more details on small, high efficiency loops.
