I built mine10 years ago and it has served me well. I earned my VUCC Satellite with it. As someone else said, it was designed with multi bands in mind.
It's a great design. I built mine for under $20.00. the biggest expense was the shipping for the caps for the diplexer, which couldn't be sourced locally.
Get out and make some Q's

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? _______________________________________________ Sent via [email protected].
