40m QRN at 9pm: 80m EFHW vs Dipole + Yaesu DNR demo

A noise comparison on 40m between an inverted vee with apex at 26’ and an 80m EFHW tuned to 1.2:1 SWR using multi-tap UNUN. Time of recording was 9pm EST (0100 UTC). I engage the DNR first at the 02:45 point if you want to skip to that

Well that’s very interesting I would have thought the dipole being a balanced antenna would have been quieter, just shows how good the uncle Blowzo UniUn is 😆. Awesome 👏. 73 de Will, M0LGW

Nice experiment. If it weren't for EFLW antennas I would probably make far fewer contacts or not even be on HF. They are inexpensive and easy to setup in challenging circumstances. I do need to wind a multi-tap UnUn like uncle 'Blowzo'. 73 to all!

Interesting video! I'm not really surprised. Should I be surprised? I'm kind of fond of the EFHW.

Are you using an unun to feed the efhw??? What ratio one???

LOL You are so funny making videos. You make videos with free spirit . Not talk like a engineear you see. And I can see you understand about this ;) 73

How high is the efhw? I have one I haven’t set up yet. I use another one for pota Cw. Any chokes or line isolation involved?
