Thanks to the innovative design by N4IS and AA7JV two TX3A DHDL have been phased in an end-fire configuration.

With the benefits of the low noise of the Pennants family antennas, and the easy of a lightweight construction, we achieve a great performance comparable to a 300 m. Beverage: over 12 dB of RDF, with a Front to Back of 30 dB and a sharp lobe at 18° angle.

All the details and pictures in this PDF paper: TX3A DHDL Rx antenna. It has been amended with the last comments from Rys, SP5EWY. He has been very successfully with two TX3A DHDL in Broadside configuration, which let him work TX3D for his DXCC # 301 on 160 meters. Congratulations Rys!

In this short PDF paper I went back to a single DHDL showing the feed system and common mode noise choking, and ….here are my final tests and comments.

 This is TX3A DHDL End-Fire tried at IV3PRK     …and this is the TX3A DHDL Broadside at SP5EWY  (far on the back ¼ wave TX vertical).
