that's some funny stuff.

What's so funny about it? It does not say the antenna exhibits that much gain. A rotatable dipole will do at least the same thing. Orienting the antenna null towards a station and then rotating it to a peak,even if that peak is down from a dipole, should show a differance of at least 10-14 dB.It is comparing relative losses,not true gains.My external tuned ferrite bar antenna will show better than 30 dB signal increase with a 90 degree rotation on the AM broadcast band. Not bad for an antenna 10 inches long on a wavelength of 200m or more. It's all about the nulls not the gains.

well after all this discusion i have one and its on the tower i see less rx then my windom which is 10ft lower then this antenna and also i see hardley any directivity out of this antenna. as many know i run cw 99.9% of time and on the windom for instance i get an s9 "599" and on this antenna pointing at them away from them on the side no difference i get an s5 to s6"569 559".. so i cant say the it has much directivity. now on foward gain.. once again windom blows it away. i receive 599 and on this antenna i get 549 to same person.. so i does make a great back up portable emergency antenna hands down but for every day use not recomended..

Just like I said,it's not about the gains but the relative losses from peak to nulls.
