Rag, the ALA1530 is not designed to compete with very large antennas like 
the Titanex V160HD or with other loops with larger apertures.



Its primary purpose is to provide low noise reception in a high noise urban 
environment. The ALA1530  has been providing this sort of service for the 
past 15 Years. This done by cancelling out the local E -field and providing 
high immunity to conducted power line noise.



Therefore, deploying the loop in a quiet location, the aforementioned 
features will not be seen.



However, if one requires, say more gain or more importantly a higher s/n 
with a Broadband loop, then a  larger loop aperture is required.



To this end Wellbrook provides a Medium aperture loop the ALA100M for simple 
wire loops say 4 to 8m in circumference or the  new ALA100LN large aperture 
loop for 20m circumference antennas.
