I've been away for a long time. Haven't run across much that I thought was worth posting until now.
I was running EZNEC simulation on a G5RV Junior yesterday and ran into the following. I simulated 40 through 10 meters on a friend's proposed installation. The plan was to put the center at 24 feet and the ends at 10 feet. The following graph shows the problem with 10 meters with that installation.
Definitely not a good DX antenna and 28 MHZ is too high frequency for NVIS operation. So I changed the simulation so the ends of the antenna are at 20 feet.
Certainly a more acceptable installation for 28 MHz.
All of the lower frequencies bands provide a more acceptable patterns even with the ends at 10 feet and moving the ends up to 20 feet made little difference to the lower bands.
Turns out even raising the entire antenna by 5 feet produces an acceptable pattern.
Just thought you'd find this interesting and hopefully useful.
