>So if you have low AC noise at LF, you could try an ALA100 with a 50-100' vertical loop, for LF-HF reception. I found the loop was quite directional; much more so than a K9AY antenna with loop oriented the same direction as the ALA100 loop. The ALA100 is also very robust for resistance to strong-signal overload. I have no strong BCB stations in this area, so overload from BCB was not an issue. (Of course the loop is bidirectional.)


The ALA100 with a big loop can be really effective for longwave as Steve mentions.  I've used one at Grayland, and it definitely snagged the longwave broadcasters better than the short Beverages we use there.  The loop also seems to resist local electrical noise better than a random wire.   But a loop that size in town, with BCB transmitters within a few miles, causes the ALA100 to overload.   But, it's the least likely to overload under these conditions of any amplifier I've used .  I believe Dallas Lankford is not quite as much an enthusiast, so YMMV, as they say.

best wishes,

Nick
