Tuning of my EFHW antenna

in STEMGeeks4 months ago

My elmer came over yesterday and we tuned my EFHW (End Fed Half Wave) antenna. While on the roof I would cut some wire from the end and Dave would recheck the SWR for 40M.

Here is a picture of the NanoVNA connected to the UNUN on the bottom of the antenna:

Here is a picture of the NanoVNA showing the SWR of the antenna over the 40M band:

The last is me standing on the roof, just before climbing down:
