Bearcat, I never owned a V58, but I remember a point in time passed when Maco announced they were no longer slotting and dressing the tapered tubing in their kits. I thought that was a big mistake...just for the reasons you note above. Using those little screw clamps to crush the tubing so it will hold fast...is not good in my book.
I don't know how much difference it makes in performance with the V58, but I have also heard it said they are difficult to tune, and as a result some complain it does not work so good. At the same time I've heard guys claim it is a great antenna, and I know some operators personally, and they talk big time using their V58 when they get it up at a good height.
Maybe you could fix the problem on your V58, but IMO 20' feet high is the bare minimum with CB...unless you live on flat land or on a hill with no obstructions around for maybe a mile or more.
Good luck,
I live in a town that gently slopes to a high point...well I am right on the highest point...but my house iS surrounded by 60-70 ft pecan trees...so my backyard has a huge opening in the middle of all these trees...i can't get over them but I could get a gainmaster up in one ?? Or just mount the Tornado on the eve of my house...i really don't know what I'm gonna do...I don't have a ton of options...just wanna get back on CB/2M
