On January 17, 2016, there was an incident where lightning struck the antenna and destroyed all radios and appliances!
My main FTDX3000 also broke and I had to buy another FTDX3000 from Tomei Denshi in March 2018 and sent it back!

But the 20mH coconut tree I was using instead of a tower.
It was cut down because it was old and in danger of falling over.

Before it was cut down, four full-size yagi antennas on three coconut trees.
Each band was attached with a fixed beam.
I'm so happy to be the owner of such a happy free tower because it's the Philippines!
A home-made 14MHz 3-elecet yagi antenna that was installed for Europe.
It flew well.
A 7 MHz dipole antenna was mounted on the remaining 20-meter pipe tower
Because the tower stands at the edge of the site, it cannot be inverted V, so it is a diagonal dipole.
The power supply part is a cutting board purchased at a grocery store
The handle part of the cutting board is just right for the coax holder.
Since the balun was not sold, I took JQ2GYU Sakurai's advice and installed 3 snap cores!
UNITRUS in the town of Osamis is the place to go for wires and parts.
Pulleys are attached to both ends of the element to allow the antenna to be raised and lowered for adjustment.
This is also the advice of JQ2GYU Sakurai-san, a DXer and owner of two cranked-up towers!
He, too, uses pulleys to adjust the low-band dipole.
The cutting board of the power feed section is machined so that no force is applied to the simultaneous shaft connectors.
It is also a folder for elements instead of corrugated insulators
Adjusting element length with NanoVNA-H4 purchased by mail order in the Philippines for 4200 pesos (about 11,500 yen)
7MHz has the lowest SWR at 7.090MHz
But 21MHz has the lowest SWR outside the band with 22.140MHz
I was looking for information on the Internet and found what I thought was information on Youtube's "Momo Channel! on Youtube.

I will write about how to put 21MHz on a 7MHz antenna in my diary on May 3.
