KY6R Big Mag Loops
I’ve sold my W6LVP Loop. It’s a very good product, and pretty close to a Wellbrook ALA1530LNP, but I preferred the Wellbrook. I do NOT like having a coax loop – its floppy and when I compared a 24′ circumference coax loop to a 3/4″ copper tubing 24′ circumference mag loop – the larger copper tubing was noticeably better (no preamps used in the chain). Larry, W6LVP offers a great product at a decent price and his support is excellent. The same goes for Andy at Wellbrook.
As far as preamps go – the W6LVP, Wellbrook and the DX Engineering preamp modules for the NCC-2 are all very low noise and very impressive. I’m sure one or the other might have better detailed specs, but to the ear, I rate all 3 of these as A+ – above average products. I know for sure that the “basic” MFJ Mag loop RX antenna is well built, but its preamp is a lot noisier than these three. However, MFJ has a new “professional” model out – maybe they have a better preamp. The loop itself was actually better built than either the W6LVP or the Wellbrook, but in the end, the preamp is critically important.
Its not a fair comparison, but my KY6R Big Mag Loops using the 3/4″ copper – plus even just the NCC-2 preamps is by far the best out of all of these products. The Wellbrook ALA100LN preamps are on their way – so I expect to even step up a notch performance wise – but its great to know that I don’t really have to have a preamp at the loops to have great performance.
I will write up how the ALA100LN’s work vs. using the NCC-2’s preamp modules. That will be one of the last tests – at least using the NCC-2. After that, I will test the NCC-1, which should be better on 40M due to its filters.
