Very cool. Did not know you could do this with the NanaVNA.

Jay - Excellent presentation! I just finished the initial work on an End Fed and counterpoise with a 9:1 match. Your description of the procedure using the Nana VNA solidified it usage in the pre-tuning stage and will make my outdoor adventures A LOT easier - As long as I can get the Antenna to stay up high in the trees!

Thanks for video

very useful video I have same equipment and now going to try it out like you show

Thanks! For this sort of tuning using the NanoVNA avoids stressing the transmitter at high SWRs.

These are nice tuners for the money. Especially having active SWR and power readings, 300 watt capacity, dummy load.

Excellent thank you

Very nice, I have a 949E too, as well as a 969 under repairing. Missing the nanovna still but will be an addition very soon.

Complimenti... ottima spiegazione. 73 de IN3KTT

Nice explanation.

Thanks!

😎👍👍

What was the total length of wire of the antenna?

OK this may be a dumb question: Is NanoVNA attached to the transmitter port of the tuner?

アンテナインピーダンスをnanoVNAは計算しているが、はたしてアンテナに電波が乗るんだろうか？
