Topband: Shared Apex Loop Array

It seems to me as a user of many types of loops of all sizes in a noisy residential area, that there is still something beyond Lower take off angle from the long beverages vs these loops, and perhaps even beyond better s/n ratio which makes beverages better.  OR maybe it's just the fact that those with long beverages are naturally in more open areas as the actual RDF, gain etc isn't that much greater from a terminated loop to a beverage to warrant the reception differences I hear on my station vs those in the general area with the beverages.  Can it be the capture area of the longer antenna is a key differentiator. ??
