Using a good inverted L can help if you can't get the height. Put us as much as you can vertical and the rest horizontal. With radials, it makes a good DX antenna. Tom W7WHY _________________________

Hi All I'd rather have a wire high up in a tree than one down low that ISN"T in a tree. I have 2 inverted V's up about 90 feet with the center in the tree's and they work fine. I used to run a vertic

Hi All Thinking about putting up a cage vertical for 80 meters. Would it be better to use insulated spreaders, like small PVC pipe, or pieces of aluminum tubing for spreaders. Thanks Tom W7WHY ______

When putting the rope between the trees, just put a pulley out a little way from each tree. Run some nylon twine through each pully in a big loop. When you get to both ends of the loop, just tie the

Hi all I just put up a 160 meter inverted L and the antenna is resonant after tweaking about 1850. It shows a resonant SWR of almost 3 to 1, but on the MFJ 259, is shows a resistance of around 40 ohm

Hi Tom The resistance reading of 40 ohms was at the low point of the SWR reading. There is a definate dip in the SWR, but it is up almost at 3:1. Tom W7WHY ___________________________________________

Hi Jerry Without all the meter readings etc, if I did have a SWR of 3:1 with a 50 ohm cable, that would mean the impedance at the feedpoint could be 16.6 ohms or it would be 150 ohms. I can't figure

One thing I did forget to mention. When I first put this antenna up last week, I hooked 3 radials about 50 feet long to it. That was all I had to test it with. I found a nice resonant point at 1.825
