I fully agree with Jeff and JC regarding the DHDL. I built my first DHDL
shortly after George's TX3A operation, and it worked extremely well.The
next step was a broadside phased array of two DHDLs, as described in an
excellent article by IV3PRK.
I don't know if the article, "RX Antennas at IV3PRK: The TX3A DHDL –
Doubling the Double Half-Delta Loop Receiving Antenna", is still easy to
find, but I have a PDF copy if anyone is interested, Luis described in
details Front-End and Broadside systems.
My second QTH is located in an orchard with very good soil, where
Beverage antennas don't perform particularly well. My "theory" is that,
since the DHDL is not connected to ground, it picks up less local noise
conducted through the soil.
I'm using a Norton preamp with about 13 dB of gain, and that's sufficient.
This broadside DHDL array has helped me work many new Pacific DX
stations that were completely inaudible on the Beverage.
Even last Bouvet was successfully worked, mostly thanks to the DHDLs on CW.
