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 variatie 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 dubbling the boomlenght.
With a boomlenght around 7 to 8 meters a 5 elements yagi  is about the biggest antenna availible withouth having to worry
to much about the mechanical problems.
