Height and width of the loop are 1 meter.
This means that one turn = 2.80 meters.
In this case i have used tree turns = 8.40 meters.
New coil value = 27 uH.
With a minimum capacitance = 35 pF the resonance frequency becomes 4.690 KHz. SWR is then 1.02.
Remark: coupling is changed to achieve a good SWR.
Measuring results:
With a maximum capacitance = 150 pF the resonance frequency becomes 2.500 KHz. SWR is then 1.13.
Measuring results:
I have tuned the loop @ 3.660 KHz.
Loop 3 turns
Compared to the loop with 2 turns (see below) te loop with 3 turns is sharper. Sharper means higher Q factor.
Loop 2 turns
