I purchased the ALA100LN from Wellbrook which is a low noise preamp ranging from 50 kHz thru 30 MHz. It ships with the power supply and must be fitted with a loop of ur choice (can be a circle, a square or a delta).
Don't make it bigger than a 21 m circumference delta loop or u experience too much signal and possible unwanted products may appear.
I utilize it from VLF thru shortwave, some time as a seperate receiving antenna with the second receiver of my Flex 5000. It has not been damaged yet by the hi power transmitting antennas which are very close to it. Compared to my ALA1530 it bring 10 to 20 dB stronger signals to the receiver but with NO improvement of the signal to noise ratio.
Any way il is interesting to experiment with different loop shapes and sizes.

I don't see just the headamp listed on their webpages so I wonder ifsomeone can buy one special order or do they sell them only as replacementsfor someone who already has one of their loops? I would need both the headamp andthe matching power inserter. Thanks for any info.73 Todd WD4NGG
