My end fed inverted "L" goes up 20 feet and then out 75 feet, with the far
end about 25' high. It is fed with a homebrew remote controlled tuner (50' from shack), simple series roller inductor and a parallel capacitor on the output. Ground system is about 6 pieces of various 20 to 30 foot lengths of wire, in a sort of random star shape, buried about 2". It generally outperformed a dipole I had up with an A/B switch to compare the two. The dipole was 25' up, 65 feet long and fed with ladder line from a link coupled tuner. The dipole was a tad quieter, but the "L" received and transmitted maybe an S unit better. I've read in more than a few places that you need to get the vertical part as high as possible before it heads on out to the woods. Bob KB8TL "blair thompson" wrote in message ... I have a 63 ft. end-fed wire antenna which I am using with an MFJ-949 versa tuner, and 4 counterpoises cut for 1/4 wave on 15,20, 30 and 40 meters. Far end not very high, about 25 feet up a tree, shot up there with a slingshot. Pretty thick foliage right now, but not a lot of the wire is showing and in the clear as the near end of the wire slopes down almost to ground level (townhome QTH). Bit of an underperformer, and I was wondering whether it would be worth my while to install a ground rod in order to ground the tuner, and whether that might improve matters a bit, Thanks for any information.
