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! Cheers! N9NAZ
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. Just remember to always start with maximum capacitance, and work the inductor to lower swr. Then ajust if needed trasmitter first then antenna cap. This way should bring you to a combination of the T network that is the best for efficiency. Of course take note of your three settings and changing band will be a piece of cake. 73
Very cool. Did not know you could do this with the NanaVNA.

Nice work! 73 du7jay
very useful video I have same equipment and now going to try it out like you show

Thanks for video
Thanks! For this sort of tuning using the NanoVNA avoids stressing the transmitter at high SWRs.
73 enjoy ham radio ✌🏻 du7jay
These are nice tuners for the money. Especially having active SWR and power readings, 300 watt capacity, dummy load.
...thats true. 73 du7jay
Complimenti... ottima spiegazione. 73 de IN3KTT
Tnx 73

Nice explanation.
Tnx 73
Excellent thank you

Thanks!
Welcome! 73 de du7jay :-)

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?
Yes sir. Connect to the trasmitter port. 👍🏻😊
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？
