The MFJ Box Fan Loop has the same size and shape as a 2x2 foot box fan, and has a carrying handle and
features an indoor tuning unit. All tuning and control voltages are coupled to the antenna through the
coaxial feedline for simple, neat, one wire installation.
The Box Fan loop antenna element is constructed from wide, thick wall Aluminum sheeting. Every
current carrying joint is welded to eliminate high resistance pressure contacts that reduce efficiency.
The Box Fan loop is tuned with a superb all welded, low-resistance, high current, butterfly tuning
capacitor.
