Ham radio herd mentality
 
Most hams who strive for maximum radiation that is horizontally
polarised place the radiator parallel to the earths surface.
That is an example of herd mentallity.
When the vectors of radiation fields and "curl" are summated
the resulting vector is NOT along the axis of the radiator.
For maximum horisontally polarised radiation it is this
vector that must be parallel to the earths surface.
By the way Maxwell confirms this but hams chose
to ignore it.
Yup, herd mentallity!

Well, that AND the fact that a 160m antenna can be difficult to
vertically polarize!

No it isn't. You slow the wave by
winding helices. Buy a tesla coil
(secondary coil) feed the end wires
and start radiating

Even a vertical DLM antenna can be a challenge, depending on any certain
individuals property/lot, neighbors and other factors ...

At 20m on down this becomes MUCH more practical ...

And, most physically short antennas introduce degraded performance--the
DLM being a notable exception.

_____________

Just to note that the URI test report showed the standard DLM on 3.5 MHz to
have about 2.33 dB less gain than the Navy's reference monopole. That means
that its groundwave field was found to be about 59% that of the reference
monopole.

Some might consider the performance of that DLM antenna to be "degraded,"
compared to a standard 1/4-wave monopole using the same r-f ground.

You two crack me up. Do you guys butter your toast on both sides so
when it falls to the ground only one side gets fuzzy? At least the
fuzzy side doesn't degrade masticating efficiency by sticking to the
roof of your mouth.

As Richard Fry has pointed out, the Navys' data is available to all ...

You crack me up too
I was just reading all your posts to John E Davis on the
gauss statics law all over again.
All handwaving about mathematics but you presented
nothing that over rides his math.
No math or is it no mass?
You got your adults degree based on your journeys in the Navy
but that didn't provide you with a mathematics regimen
to fault Davis did it?
You never wrote anything that wasn't "fuzzy"
Whant to prove my initial post in error
or return to your fuzzy logic suitably scrambled
so that it cannot be deciferred?
Try proving my initial post on this thread is in error
but then you can't so you will resort to handwaving.
Yes, Krauss, Maxwell Gauss and many many others support it
but you, you are not equipped to oppose

The Real "Ham radio herd mentality" is also demonstrated by the number
of hookees swept up by these trolls.
