A high-performance 80/40 meter vertical. Full size quarter wave radiator for 40 meters – that’s 33 feet of ruthless radiating power. End loading, low-loss fiberglass form, high strength 6061-T6 Aluminum tubing, handles 1500 Watts PEP, requires guying and radials counterpoises or ground screen.
The MFJ-1793 operates as a full quarter wave on 40 and 20 meters, and a top loaded 1/8 wavelength antenna on 80 meters. When used with a good ground system, the MFJ-1793 has excellent efficiency and bandwidth on 40 and 20 meters. 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.
