Re: [IRCA] Wellbrook Large Aperture Loop Antenna ALA100LN



I use a diamond shaped loop of wire ~80m for my ALA-100 and hung from  35m
high.  This size is just on the verge of overloading from my locals, which
are 80 km away.  This size seems to give good performance in general but is
not exceptional on longwave bc. For example, 189 Iceland is often very
listenable on the Eu beverage  but generally just detectable on the loop.
