I use salt water clear fishing-leader line for my wire antennas
my wire antennas go to a couple of nicely convient BIG trees.
The one tree is in the parkway in front of my house.
I use a casting fishing rod to throw a 2oz. lead weight over the top of the tree and let the weight decend.
Here is my little trick that solved the line breaking due to rubbing on the branches but still allowing the antenna to change height as the tower is raised or lowered pending weather conditions.
After I get the weight to the ground I attach this monofilament, almost clear and practically invisible SALT WATER FISHING line that's used for the big salt water fish.
Over 3 years of rubbing, going up and down in that tree (old iron window sash weight) and has never broken. (you youngsters probably don't know what a sash weight is) Previous types of line always succumbed to the effect of wind induced abrasion.
And if your wondering, I do have a much heavier rope from that sash weight to a limb so just in case the mono does break, the weight doesn't do any damage to my already feeble head.
I saw a note about this stuff in some antenna website. Cheap, very cheap end runs on ebay, and it comes in various 'test' weights.
I presently have 500# test which I have to strain to see and I know where to look. I don't bother with end insulators either.
The line comes with a supply of small crimps. I started trying knots and they just slid right out. So ended up using a bowline AND the crimps and they haven't slid out yet. Oh, and it has NO streching.
Now after some medical problems, my wife insists I can not go on the roof to replace this fishing line if it does break.
So has anyone yet used one of the remote gyrocopters to drag a light line over a tree? and then use that to get the strong stuff in place?
My only worry...I'm just about 3/4 of a mile south of the main landing runway at Ohare. LOL
Do you think they would yank my license? The tree is about 60 feet at the peak.
