The MFJ mag loop antenna has a very narrow bandwidth. Using my Flex Maestro, you can see this demonstrated on the bandscope.
This MFJ 1786 Super Hi-Q loop Antenna is 36 in. diameter loop antenna that works on 10 through 30 MHz continuously, including the WARC bands.
They're good for limited-space applications like apartments, small lots, RVs, attics, and mobile homes. They mount vertically, so you'll enjoy both DX and local contacts.
They exhibit low-angle radiation for excellent DX and high angle radiation for local, NVIS close-in contacts; all while handling 150 watts.
Only MFJ's super remote control has auto band selection. These loops automatically tune to the desired band, and then beep to alert you. Since it's done over the coax, you don't even need a control cable.
Fast/slow tune buttons and the built-in 2-range cross-needle SWR/wattmeter let you quickly tune to your exact frequency. With all-welded construction, no mechanical joints, a welded butterfly capacitor with no rotating contacts, and a large 1.050 in. diameter round radiator (not a lossy flat strip) these loops give you the highest possible efficiency.
Each plate in MFJ's tuning capacitor is welded for low loss and is polished to prevent high voltage arcing. They're welded to the radiator and have a nylon bearing, an anti-backlash mechanism, limit switches, and a continuous, no-step DC motor that gives smooth, precision tuning. The thick and heavy duty ABS plastic housing has ultraviolet inhibitor protection. These antennas require a 110 V input at the included controller power supply.
Is your space limited? Get on the air anyway with MFJ 1786 Super Hi-Q loop Antennas.
