10MHz, 14MHz fan-out antenna (2025/04/20) 
10MHz and 14MHz fan-out antenna installation complete
I started working at about 7am, and didn't notice that the fan-out elements were tangled.
It took me until noon because I had trouble adjusting the tuning point, which was way off and the SWR was high.
Although we worked under the scorching tropical sun, we were able to achieve satisfactory results.
So, this is my first time using 10MHz. What kind of band is it?

I felt the danger of working under the scorching tropical sun.

This means we can now broadcast ON AIR on all bands except 1.9 and 3.5MHz.
The 3.5MHz antenna is also a Zepp antenna from Japan.JK1SNSI had it sent to me from
I was unable to buy the coaxial cable and winter ended up being the end of the day.
5cm x 30cm acrylic plate for holding elements

The element length is
10MHz is 6m70cm
14Mhz is 4m80cm
I measured it with NanoNVA and asked ChatGPT how many centimeters I needed to adjust.
On the right is the 7, 21, and 28MHz antenna.
The antenna in the middle is the 10 and 14MHz antenna we made this time.
The left side is the 18 and 24MHz antennas.

All are fan-out antennas.
