Not likely.  The primary determinant in take-off angle for any
horizontal antenna is height.  While a well designed yagi will have
a slightly lower take off angle than a dipole due to the reduced
radiation from the top/bottom the effect is modest.

Hello group and once again I thank everyone who helped with my
previous post about the concrete.




My set up: Mosley TA 33 JR tri-bander that will be at about 31 feet.
The question:  I've been debating ways to get at 40-80 meters. I have
a very small lot so cant run the usual wire suspects and was thinking
about making a mag loop.

But I've also thought about an end fed Chameleon or 33' Ultimax at
about 28 feet as I do have room to run one of those horizontal to a
tree. These are multi-banded antennas but I've never given considered
using them on 20,15,10 of course.

But then a thought occurred to me. Might the take off angles of the
wire antenna be different enough as to be beneficial for transmitting
on those bands and hitting different spots of the globe that the
Mosley is skipping over? 73, David, AA9G
