Better to shorten wire on end insulator and wrap it around itself than to cut it. This way you keep the full capabilities of the
antenna for future use. Also, the PSK and RTTY areas of the band are close to the CW area.

This way, you can cut them shorter to work on the SSB portion of the band.

Any Advise? Gayle KF5LVZ On Mon, May 8, 2017 at 11:35 AM, Gayle Dotts <gayle.do...@gmail.com<mailto:gayle.do...@gmail.com>> wrote: Thank you guys. I orientated the wires so that I could with little effort switch directions to accommodate. The degree of angle off straight up and down I can play with. Elevation on the mast in an inverted V is around 35 feet. Gayle KF5LVZ PS: I will say this from a 10M rotatable MFJ 1980 Moxon type antenna to now a new Alpha Delta DX EE........ For observations on the 20M, 40M and 80M........traffic feels like it has increased 70% on all bands with stations I had not heard before or the ability to hear before. The 10M I will have to observe using the 10M nets coming up to comment on.

If you don't know where you want your signal to go, or don't yet care, then do what people typically do and put it up in whichever direction is most convenient. If you've got the money, the time, and the space, you can always set up two of them at right angles to each other and switch between them, depending on which one brings in the louder signal. As far as making it straight goes (I think that's what you're asking, if it's not, then please correct me) then as long as the legs aren't too close together it won't have a huge effect on the radiation pattern. A right angle is probably not "too close". I don't believe that the radiation will be substantially less efficient, but you may get the energy directed in a peculiar direction. The thing is, unless you know what you're trying to achieve, the thing to do is to put something up and see what you get. If you find that you communicate really well to nowhere you want to talk to, then consider making changes or even trying your hand at some modelling to see what it's really doing. The thing to understand is that all antennas interact with the environment that they're in. That means that unless it's well isolated from nearly everything your signal will go off in weird directions because it's near the metal in your house or a shed or a fence or whatever. Trying to anticipate that is of limited use, and probably not worth the effort until you know what you're trying to do.

I do know that broadside is where most of my signals will come from...or does it really matter?? Also usually one sets up dipoles wires so the combined asmith is close to 180 degrees. Can I do a 90 degree combined asmith...... or will that decrease my signals? Thank you for your thoughts guys, I appreciate it!
