As some of you know, I had to raise my Eastern beverage a couple years back, when they took the old fence out. I raised it for the first 450 feet. After that the fence is still there and it runs back on the fence. The first 450 feet runs up to 15-16 feet, so the farm equipment can drive under it through the gate. It was not my choice, but that was all I could do if I wanted to keep the beverage. The directivity of the beverage has been comprimised alright, but it still works. Everything I have heard or read is there are not supposed to be any sharp vertical leads, even down to the ends. Well this evening I tried a bit of changing the end to the matching transformer. I had it slowly sloped down to the about 2 feet off the ground. I took the end loose while monitoring the signal by rebroadcasting the R8 so I could listen outside on a portable. I went on a couple frequencies like 1100 and then 740. With the antenna slowly sloping down I got basically KFAX SF on 1100 off the Eastern beverage which is South of me. Not good. I then moved the last 10-15 feet of the wire higher on a branch bringing the wire straight to the tree without any sloping and then a straight downlead to the matching transformer box. I suddenly got about 50% of Grand Junction CO that wasn't there before. So I thought, Interesting. I went returned the R8 to 740 and had a fairly strong KCBS, also South of me. Also not good. I then moved the antenna back up to the branch for the second time, and brought the wire straight down as I did before, KCBS was gone leaving noise. Tonight later I hear a weak KCBS and CBX. The beverage worked much better at 4 feet off the ground on the old fencing, but unfortunately that is history now. But I am trying to "Have my cake again and eat it too" sort of thing. But I was amazed that changing the last few feet of the wire made such a difference. I could always extend the coax and move the matching transformer up higher straight in and use a bit longer wire for the grounding going down vertically. I have no idea how that would work. But at least in this case the slanting down lead does not help the directivity of the beverage. Any comments? Thanks.
