I've spent some time working on a low noise antenna that can also be used on transmit. After doing some antenna modeling and building a working prototype I made a web page for the new antenna design. I've now added an update to the web page following feedback from users and questions I've been asked about it. It's a simple antenna to build and offers wideband HF coverage with low noise performance with a simple earthing or grounding system. The web page is: http://www.crosscountrywireless.net/terminated_inverted_u.html 73, Chris, G4HYG
I suggest you move that to the Antenna Forum on QRZ where it will be seen and commented on Im sure. https://forums.qrz.com/index.php?forums/antennas-feedlines-towers-rotors.33/ Carl
