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 m
Holy YMMV. Thanks for your great posting of what most of us didn't know (I know I didn't). Do you have any numerical data concerning the ground conductivity in VK6 vs the VK east coast? The conductiv
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 u
Hi Rick and Steve, Steve's QTH is almost directly north of the south geomagnetic pole. His latitude is approximately 32 degrees south geographic latitude and approximately 43 degrees south geomagneti

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 throu
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 th
Hi Frank (and Rick) Somewhere I have a map of the lines of geomagnetic latitude superimposed on a Mercator projection of the world, but I cant find it right now. Unlike the ruler-straight lines of co

Hi Steve, Low band Dxers,, Some of the trials involving 5/8 wave verticals on the broadcast band, and 160 meters preformed poorly. Optimum take off angle is quite a bit higher. 73 Bruce-k1fz Hi Frank
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 revis
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
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 bette
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
