[amsat-bb] dual band vhf/uhf antenna

[Jackie Dander]

I built the combination dual band 2meter/70cm antenna found at WA5VJB's
webpages. I chose the 5 elements on UHF forward and 2 elements on VHF rear.
All elements are in the same plane.
I now read elsewhere that in-same-plane uhf/vhf elements can interfere with
each other. I visited the Arrow website and see their LEO antennas are
opposing for uhf/vhf.
My question is if i made a mistake building the uni-plane version? Why did
WA5VJB has such success?
