JI1FGX/DU9 7MHz full size dipole（May 21, 2011)
Always connected at HFJA1FVS Mr. MoriyaAnd while I was talking about the 7MHz rotary dipole, I made one myself!

This is the rotary dipole made by Mr. Moriya
The coil is beautifully finished, but the artist says he went through various hardships during the production process, such as burning the coil.


it is said that ...



burnt coil
Diameter 22.5mm, 19mm, 16mm connected
I wound the loading coil with 0.8mm copper wire, but it did not last 50w at continuous transmitting output and caught fire!
Finally, 1.6 mm diameter enameled wire was wrapped around a 32 mm diameter PVC pipe and sealant was applied over it
So I built a 7MHz full size dipole
Of course, one side of the pipe is 10 meters long, and if only aluminum pipes were used, they would be bent like this.

Of course I know I can shorten it by adding coils, but it's too much trouble to find the material, so I'm going to take the easy way out and use a full-size

4m of 25.6mm pipe
19mm pipe is 2.3m
12mm pipe is 3.7m
So I hung it up with a tegus, and it took on a shape that looked reasonably usable.
The installation will still take some time because Lotlot and other workers are busy with other projects.
