[amsat-bb] dual band vhf/uhf antenna

[Rick Tejera]

Jackie,

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?
