Hi NG

About ready to model and build a medium 2m antenna system. Probably run
a EDZ with 5/8 elements off one side of the mast for vertical and a
three element wide spaced thick element quad for horiz on the other
side. The mast mount will form part of the model when I get to it.
(Hoping for a cardioid pattern from the EDZ)

Main element material for both antennas will probably be 1/2" copper.
(That will make the quad interesting to support!)

Sticking to the vertical system I am wanting to get a handle on how
important the "problem" of desired low angle radiation is and what traps
one should avoid. I am aware of the mast/coax decoupling issues. I also
believe that the narrower the vertical beamwidth (or rather the less
downward radiation) the less the ground reflection problem will be.

Also wondering if adjusting phase delay or amplitude variations between
the 5/8 elements would be useful in lowering the pattern. (Something I
will also be modelling) Feed would probably be a 4:1 coaxial balun.

Height will eventually be about 30ft above the house roof.

Any thoughts, ideas and debunking most welcome
