Now that the solar cycle is really ramping up, I’m thinking of making a extended double zepp for 10m. Has anyone tried this and or used one? I see QRP guys makes a 1:1 balun kit.
I found this article below. Still trying to see if 300ohm ladder line would be a better (lighter choice) albeit maybe no as efficient as 450ohm?
Instead of viewing that as a 10m EDZ antenna, look at it as the classic 44ft doublet, aka “NorCal Doublet”. This is a very popular antenna, and you’ll still have all that gain on 10M and it will work fine on 40-12M as well. You need to use a feedline length that won’t create matching problems with your tuner (i.e., 22ft plus feedline length x VF is not a multiple of 1/2L). You can use 450-ohm, 300-ohm or other balanced lines. I’ve used CAT5e twisted pair (PTFE insulated) as a superlight option and it worked well, although 300-ohm would be lower loss. Good luck!
If you don’t want to have a matched antenna on a specific band and you like to use a tuner, there are plenty of good options here… in all possible lengths and radiation patterns.
