MFJ Super Hi-Q Loop™ Antenna Instruction Manual
If the slow tune buttons tune too fast to tune properly.
As above, adjustment of R26 is necessary. Adjust R26 for a slower pulse (LED blinks slower). Note
that improper adjustment of R26 will cause the problem above. Check for tuning on all bands before
reinstalling the cover.
If SWR is high due to close proximity to buildings, wires, trees, etc..
If SWR is high due to placement of the antenna, the feed loop in the antenna can be tuned (shaped) to
get a lower SWR. Remove the bottom shell of the weather cover by removing the 20 screws holding it
together. Locate the feed loop, a loop of 10 gauge wire connected to a pcb at the feed point. The loop
may be circular or elliptical. Compress or extend the loop until swr is at an acceptable level. Replace
the cover.
