Well guys I decided to do my test of my A99, with and without a feed line again. This time I isolated the antenna from the mast, just in case that made the difference in what I saw testing this same idea several year ago.

Here is a video I did today in about an hour that shows what I saw.

All I'm trying to do is to check and see if we don't have a feed line or a mast on the A99, will it ill-effect the match...since according to many claims this end fed half wave must have the other half of the antenna to work right.

I recall that Northern35, did this test with his analyzer a while back, but his results were way off. I think that is exactly what he was expecting to happen. I also guess that convinced many that my idea was not so good, so I decided to try the comparison test again, and do a video to see if I could duplicate what I originally saw and here are those results.

What do you think?
