nice work but i do not like it.. why end of coax is not grounded and closer to meddle point od loads.. . need to be wavelength coax velocity.BriansBrain wrote: ↑Tue Apr 25, 2023 6:11 pm![]()
I know that the SWR is not gonna be perfect![]()
Finished putting it together today, gonna test it tomorrow![]()

It's directly on the heatsink, if you look caefully you can see the cutout
Thanks
Will that help ?
Thanks
Thanks for the suggestionsjvok wrote: ↑Wed Apr 26, 2023 6:39 pm I bet if you shrunk everything down you could get it a lot better than that. Put the resistors right next to each other so you can solder straight between the pins and get rid of the wires in between. Also see if you can solder the pins at the end of each chain straight down to the copper instead of wiring to a solder tag. You might need a torch or at least a really big iron to get the copper hot enough.
I understand that now
Well considering the cost.......... and that I made it........ it's not that bad then

I knew I was not gonna have a perfect dummy with this design from the start
