MFJ-57B PVC Cross Loop Antenna Kit
Introduction:
The
MFJ – 57B PVC Cross Loop Antenna Kit
is designed to be used along with the
MFJ-
933, MFJ-935B and MFJ-936B
Small High Efficiency
Loop Tuners
to provide coverage
on 10.100 – 14.350 MHz by using only one loop length. The length provided in this kit,
13-feet, is designed to be most efficient on 14.350 MHz, and the loop can be tuned lower
in frequency with some efficiency loss. Exact frequency coverage and efficiency depends
on each individual installation involving shape of loop, height above ground level, and
operating environment.
