I was thinking of buying a real Wellbrook 1530 antenna before it closed down. But then my Active Mini Whip and Random wire + ATU were doing good DXing LW MW and HF, so I didn't bother. I used to have a real wellbrook 1530 loop before, and have been DXing with it for about year. It was good in some part of the band, especially on LW and MW, but on HF, it was similar to much cheaper MLA30. And there are plenty of ferrite rod, and loop antennas to build and test on LW and MW, which can be more fun.
Anyway, I compared my youtube SWL log copying Myanmar Radio 5985 kHz with the real Wellbrook 1530 loop a couple of year ago, and one I copied this spring a month or two ago with Random wire + ATU. The random wire were copying 10 times better than the Wellbrook 1530, so I was glad I didn't throw away £300 for another Wellbrook 1530LN. The old one was sold, when I went QRT, and saving every penny and selling most of my radio gear for funding to buy electric guitars 2 year ago, which I regretted at the time. But now I feel random wire, Active Miniwhip and even cheap MLA30 will do the same job or even better job provided they are set up well for the environment of RX location.
