I want to build IZ2UUF’s lightweight 2M yagi:
Any designs for such to resonate at about 146.5MHz call for elements to be 850-1000mm long (33.5-39.5"). If you live in Europe that is not an issue because all aluminium TIG rods come in 1m (39.4") lengths. However, here in North America almost all such TIG rods are only 36" long. Yes, can order an entire box of 1m rods for ~$100 but I only need 4 such rods. I have approached a number of welder’s supply outfits and smaller welding shops with the same response.
I understand that a propane torch can get these rods to melting point so am considering trying to weld a small extension piece for at least the reflector and driven element lengths, but not sure how robust such would be.
Any other ideas appreciated…
