I built a temporary spiral loop, for 40m. I am working out the bugs with finding the correct tuning capacitor for this design. building from design by N4SPP. Have two unknown value air variable capacitors, neither would tune 40m by themselves(too high pf value) currently in series and now in range.

I have but my dipole up again after trying an end fed long wire with tuned counterpoise. I am running wspr to see how well this antenna works at this location. will later try building a magnetic loop, I like the idea of having an effective antenna for my small lot.
