For the 80 m band the coil is wound with black 1.5 mm² installation wire of approximately 10 m length. The antenna resonates at 3,630 MHz with this

Inverted-L for 80m & 160m
On 80m very good performances with very acceptable noise level. Made several comparisons with EWE antenna's and magnetic loops - the very weak stations were always readable

80-75 Meter 4-Square Array
The SWR from 3.5 to 3.9 is below 1.5:1, the F/R of the array is 20dB average and with some signals even better
