Hello fellow ham, I am looking for a 40m to 10m antenna design. I cant mount it vertically therefore it must be horizontal. The thing is that I don't have much room in my roof to mount this antenna, so I was looking for the best length/performance relation. I can consider folded loop, trapped loop, or like G5RV or even W3HH design. The maximum length should be around 50 feet / 15 meters or less... Could you please give me some help on this?
