Locked Re: Loop options for HF RX

I am sorry that you didn¡¯t receive a reply from the Wellbrook website. This may be due to my server junking some emails or an oversight.

Working on the assumption that you may not require the high gain ALA1530LNPro.. Then for 160-10M; the ALA1530 and the ALA1530LN would provide the best overall performance. If you intend the use your loop in a low noise environment then the ALA1530LN has the lowest noise amplifier
compared to any other active loop on the market in the sub $1000 price range.

If space isn¡¯t a premium then the lower price ALA100LN with a 2m square wire loop will out perform any 1m dia. loop

Kind regards

Hi All,

This has proven to be a very informative group so far, appreciate the information and willingness to share.

I am looking for a loop that to be used as an HF RX antenna (160-10m) in an urban environment. The main purpose is to use to null out local noise. I don't do much SWL or any receiving below 160m. I had an MLA30 and was impressed with the improvements it had, however did find that it was primarily useful on 40m for me, but was not much better than my dipole on 20, 15, 10. The MLA was damaged in a windstorm (due to my having replaced the wire with an aluminum flat bar loop, the impact destroyed the amplifier). But whatever loop I do get will be on a 10ft mast cemented a few feet into the ground, with a rotator. I see lots of reviews and comments on the performance of various loops on bands lower than 160m. While I don't mind good performance there, that is not my primary need. Primarily I will be using on bands higher than 160m.

So, given that criteria, I have been looking at a variety of loops on the market.

  • DXE/Pixel option looks nice, but the nearly $600 USD once shipped is out of my price range for this project.
  • MFJ 1886 or a W6LVP loop for less than $350.
  • Wellbrook for less than $400 USD as well including shipping, if I am doing my math correctly.
  • Chameleon RX Loop looks to be a very expensive ($500) copy of a M0AYF design?
  • DIY with a LZ1AQ loop amp. I'm not opposed to building my own, I have aluminum bar, copper pipe, PVC and can solder just fine. if a $100 DIY loop will perform on HF bands nearly as well as $300 loops, I don't mind going with that option.


Any thoughts given my use case, which may be better suited for my needs? If Wellbrook is a great option for me, I would also need help determining if the 1530 or the 1530LN is the best bet for me as well. I would assume the LN option is better - but someone more knowledgeable can tell me if it will be better on 160-10m or if it may be more suited for reception below 160m? I did send a message via Wellbrook site a couple weeks ago on the options and what may better suite HF RX, but unfortunately did not receive a reply.

Thanks all!
