I'm very new to ham radio, licensed in the last few months. I'm trying to build a coax collinear for 70cm following designs like:
I've modified the materials a bit, I'm using LMR400 for the elements. My question comes from the balun aspect. I don't understand how baluns are designed and the methods I'm using call for toroids and a copper tube to be placed on the feedline.
My questions are as follows:
Thanks
I've modified the materials a bit, I'm using LMR400 for the elements. My question comes from the balun aspect. I don't understand how baluns are designed and the methods I'm using call for toroids and a copper tube to be placed on the feedline.
My questions are as follows:
- FT50-43 toroids (called for in one design) won't fit over LMR400, so I ordered some FT83-43s instead. Will these work properly?
- Are there other easier options for the balun than the copper tube, toroid method?
- Some folks have commented that these designs don't really work. Are there folks who have built these who know how well they work?
Thanks
