JI1FGX/DU9Fabrication of Antenna for EME（2011/07/29)
I bought an aluminum pipe at the glass store I always go to in Osamis.
Three 22-foot lengths of 1-inch square pipe and two 9-mm round pipes
Material cost 5440 yen
We are planning to build a 17-ele antenna with a boom length of 12m
Two are booms, but one is a support for the boom from below

The drilling machine was borrowed from a glass store
I first pre-drilled the hole with a thin drill and then replaced it with a 9m drill.
Working with me was Charlie, the manager.
Here are the values I recalculated for 50 ohm direct feed

7ele YAGI 144MHz EME
