Hi, I am a new member of this group. Callsign HB9VQQ.

I have been experimenting with Loop antennas for some time. I have been using a Wlelgood 3.1 loop with a diameter of 1m (single loop) for many years. When I came across the Mag-Loop calculator, I was curious to see if I could improve my RX with a new design. So I came up with a new design with the main focus of reducing inductance and increasing conductor area.

I finished building the dual parallel loop yesterday and put it in operation. I am using a Wellgood 4.1 Amp. Wired like this. Should I cross the connections?

More Info can be found at /g/wsprbeacon/topic/bigger_wellgood_loop/110398954

So which of the two is better? I use WSPR to compare the decoding performance with my “old” Wellgood loop with 2 RX-888 Mk2 and wsprdaemon. This allows simultaneous WSPR decoding on multiple bands. In my case from 2200 - 40m band (bands of interest).

This is my test setup to compare the performance

The results can be seen here (still running at the time of this writing). I am not overly happy with the results, especially with the DX Spots (Distance > 3000km) on 40m.

?

I am not sure if my 2 parallel loop design is a good one, maybe 2 crossed parallel loops in the same plane (LZ1AQ) would be better. Also, I am not sure if the Wellgood Amp is well suited for this setup.
