There is no such things as "best antenna".
When I lived in Arizona, I had on a hill-top a doublet with 300 foot arms at
100 foot height (effectively more because of the hill-top). I used it both
as a doublet and as a vertical T (with the two wires of the ladder line
shorted). It had about 40 ra
Have to remember that W8JI, ON4UN and many others were not lying or
deceived. What we are finding out is that a major rule has some exceptions.
If you're talking to a club member in the US, you better point them to
verticals, T's or inverted L's.
One of the missing aspects of dipole vs. vertical c
It just dawned on me that the reason why an inverted-L works so well for
many is because it radiates both vertically and horizontally.
Remember W8JI's experience where a nearby ham, using an inverted-L on a
small city lot in Toledo, Ohio did nearly as well as Tom with his 120'
tower with 120 full
This has been an eye-opening discussion for me! I have always preached the
'gospel' of vertical-is-usually-best based on W8JI, ON4UN, and *many* other
long-time Topbanders. Someday I'll have to revise
www.w0btu.com/160_meters.html and include a link to this thread.
I stand corrected. Thank you, ge

Hi Frank
I can comment on horizontal polarization. I am experiencing both polarization
since 1980; with a vertical and a inverted V at 30m and 40m later; also with
high DRF receiving antennas like the HWF and VWF since 2006.
Here my 2 cents.
There are 3 steps.
1. Make the
What Steve and Nick VE7DXR were referring to is the geomagnetic latitude in
relation to polarization - not ground conductivity.
This involves the ordinary and extraordinary waves that propagate through
the ionosphere, and how 160m is affected by being close to the electron
gyro-frequency.

Its difficult to use Geomagnetic latitude as a basis of conductivity because of
variables.
Robin VK6LK lived in Margaret River, Western Australia, and salt sea water was
a few feet under ground. He used vertical antennas effectively. He caught rain

Holy YMMV. Thanks for your great posting of what most of us didn't know

Hi JC
In my experience, here in the southern hemisphere and relatively close to
the equator, I wish that "Vertical TX antenna is the only way to work DX on
topband!"
Unfortunately vertical antennas mostly don't work here well where I am in
south-western WA - there is too much ground loss in
