Hi, Andreas Well, it's interesting. I could try modeling it in EZNEC, Have you tried that?
I wonder a bit about how good the cancellation is between the horizontal wires, when the lower one is only 10' off the ground, but a model might provide some insight! (I'd wonder a bit too about the proximity of the vertical portion to the tower!) Good luck with it! 73, Charlie, K4OTV -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Andreas Hofmann Sent: Tuesday, September 24, 2013 2:24 PM To: '[email protected]' Subject: Topband: Double L antenna as an alternative for the radial-challenged? Hi, I am looking into what it would take to put a decent 160m antenna up. I got many large trees, but also rather thick woods, and the radials are always something that I do not enjoy much. Also, I cannot see myself to do 16 radials. 4 elevated radials may be tough as well. Terrain is just not as easy to get around. Now, I am looking at options that do not require radials and still have a decent radiation angle for DX. I am looking at this antenna http://www.yccc.org/Articles/double_l.htm, the double L antenna. Has anyone experience with it? What is the pattern of it and can it be compared to a quarter wave vertical? I would assume since it somehow resembles a vertical dipole and therefore does not require any radials, that its efficiency should be much better than a quarter wave vertical with less than adequate number of radials... Are my assumptions correct, and are there any other gotchas? Thanks and cu soon on topband Andy, KU7T _________________ Topband Reflector _________________ Topband Reflector
