Connecting NanoVNA, antenna, and manual tuner


 

Hello all,
I would like to connect my NanoVNA, antenna and manual tuner (MFJ-969).
I can connect the nano and antenna but am not sure how to bring in the tuner.
An example of what I am trying to do can be found here:
at the 3:43 mark.
I have found several videos similar to the above video but unfortunately they don't show their connections.
Thank You,
Steven/kc3dow


 

Steven,
[Transceiver], [Tuner], [Antenna] = [Nano], [Tuner], [Antenna] Set up if you wish to use your tuner to "adjust" your antenna resonant point with your Nano.

Using a smith chart VNA with a manual antenna will be an eye opening experience. You will never want to go back to the hunt and peck method of the three controls.

In its simplest form you will need an sma to uhf adapter that will connect your nanvna to the tuner in place of your transmitter.
Watch the smith chart along with the swr and or logmag curves while you tune to the frequency you want to work.

As Lester said, its very educational and you just tuned up without transmitting.

I can send you a pic if you need it. Hope this helps.
