I’m not quite ready as I haven’t bought a house yet, but, I will be buying a house this year hopefully. So, I’ve been giving some thought to homebrew 11m antenna design.
In particular I’m thinking about something low profile, probably a wire antenna of some sort. I initially thought about a simple centre fed half wave.
But, what about an end fed half wave wire with a balun?
I’m not particularly worried about gain, or having something that is omi-directional, and I understand polarisation issues.
So, if I go the balun route, would a 4:1 be suitable?
I'm not sure what the impedence is at the end of a 1/2 lambda antenna (there's plenty of reference to it on the web) but it is way way outside your 4:1 balun ratio and is more unun in nature, for simplicity I'd stick with the dipole or maybe a 1/4 lambda over ground plane type antenna
