It is worth changing the loop size in the calculator to get the best efficiency possible in your favorite band. For example, my 30-10 Meter loop is 8.5 ft in circumference and 23% efficient at 10.1Mhz but 91% efficient at 28Mhz. This represents a difference of about 6dB or 1 S-Unit. The diameter of the conductor determines its resistance and ...
