Using the MFJ-1788 Mag Loop Antenna Horizontally

“I test the MFJ-1788 in a horizontal position on my rooftop. The performance is great on 20m. I used an MFJ Cobweb antenna as the comparison antenna”

MFJs tiny 36 inch diameter loop antenna lets you operate 15 through 40 Meters continuously — including the WARC bands!

Ideal for limited space — apartments, small lots, motor homes, attics, or mobile homes.

Enjoy both DX and local contacts mounted vertically. Get both low angle radiation for excellent DX and high angel radiation for local, close-in contacts. Handles 150 Watts.

Super easy-to-use! Only MFJs super remote control has Auto Band Selection. It auto-tunes to desired band, then beeps to let you know. No control cable is needed.

Fast/Slow tune buttons and built-in two range Cross-Needle SWR/Wattmeter lets you quickly tune to your exact frequency.

All welded construction, no mechanical joints, welded butterfly capacitor with no rotating contacts, large 1.050 inch diameter round radiator — not a lossy thing flat – strip — gives you highest possible efficiency.

Each plate in MFJs tuning capacitor is welded for low loss and polished to prevent high voltage arcing, welded to the radiator, has nylon bearing, anti-backlash mechanism, limit switches, continuous no-step DC motor — gives smooth precision tuning.

Heavy duty thick ABS plastic housing has ultraviolet inhibitor protection.

Requires 110V input power. See MFJ-1788X for 220V version
