The MFJ-1792 operates as a full quarter wave on 40 meters, and a top
loaded 1/8 wavelength antenna on 80 meters. When used with a good ground system, the
MFJ-1792 has excellent efficiency and bandwidth on 40. No
loading coils are used on these bands. On 80 meters, the antenna is a very efficient top
loaded antenna. Top loading is the most efficient loading method known. It is top loaded
with a loading coil, wound on fiberglass with Teflon coated wire.
