I made a reception comparison between Wellbrook ALA1530LN and YouLoop antennas. Measurements have been made with an Airspy HF+ Discovery, indoor (in a noisy environment with a lot of SMPS), during daytime and both antennas were pointing approximately northeast. Measurements with Wellbrook's antenna have been made with Airspy's HF preamp at off. I didn't change antenna during each measurement. I started measurements with Wellbrook's antenna and changed antenna at the end. MSF time signal measurements have been made at the end of all measurements (approx 1 hour).
Transmitter (frequency in kHz) YouLoop (dB) ; ALA1530LN (dB)
--------------------------------------------------------------
DHO38 (23.4) : 37 ; 40
GYW1 (51.95) : 21 ; 24
MSF (60) : 31 ; 35
GYN2 (81) : 30 ; 33
DCF39 (139) : 38 ; 41
TDF (162) : 77 ; 78
RTL (234) : 66 ; 66
BV (391) : 25 ; 27
Wellbrook's reception is slightly better on LF. I haven't tried to use Wellbrook's antenna in a calm environment yet.
