ELEMENTS YAGI
The serious DXing machine !
These antenna
types are worth the effort, the expensive rotator will pay for every
penny you have spent.
I myself worked 100 DXCC in half a year during the sunspot minimum (2005
sep-2006 feb) with an antenna like this.
Rob who has a 5el ITB version has now 298 DXCC great job!
They come
in a great variation on the market short versions...long versions etc..
As said earlier when you want a significant change with your antenna
system this will come down to almost doubling the boomlenght.
With a boomlenght around 7 to 8 meters a 5 elements yagi is about the
biggest antenna available without having to worry
to much about the mechanical problems.
