Guy, I actually composed an explanatory note to go along with that picture but it didn't post for some reason. My guess is that said note is sitting there on my big computer waiting for me to hit the "submit" button. The way I do this when posting a picture is to do so from my phone then "edit" the post to add any needed text. I am now composing this message from my iPhone.
The idea behind the fence is to trick the deer. A deer can jump really high or he can jump really long. However, he can't do both at the same time. So putting a tall fence on a slant and marking it with something easily seen by a deer (white marking ribbon) creates a psychologically impossible jump. That leaves the deer with only one other option - going through. By attempting to go through the obstacle, he is directed into the hot wire, the shock of which let's him know that going through the fence isn't an attractive option so choosing the least of all evils, he stays the heck out. Mission accomplished.
The unit is a solar powered Fi-Shock SS-440 Low Impedance Medium Duty Fence Energizer which is rated to energize 5 miles of fence and our fence is a smidge over 1/4 mile long. The hot wire is a Poly Wire and all the others are the plain metal wire normally used for electric fencing. The most frequently used and in retrospect the diameter preferred is 17 gauge. The metal posts are 6' tall and the wooden posts are treated 2 x 2s. The 2 x 2s were affixed to the metal posts 4' from the ground and the base of the 2 x 2s are 4' from the base of the post. The 2 x 2s were affixed using the same wire as was used for the fence itself. The fence consists of the one hot wire and 5 dummy wires. The dummy wires will all have white marking ribbon tied onto them to create that 3-D image because a deer sees in black and white so something pure white becomes very visible.
The beginning and end points of the fence are treated 4 x 4s that were salvaged from the kids' playhouse that survived the move perfectly from our old house to our new one until we went under that low slung cable that pulled it off the trailer and converted that seldom used waste of money that I told my wife in vain that it would be to MUCH more valuable scrap lumber.
I have no idea how long the unit will hold a charge as I was merely following the recipe as given by a fellow who reportedly had great success with an almost identical set-up.
The number of hot wires you can have is situationally driven. If rabbits are a problem, an additional, energized wire can be added at any height the user deems appropriate. We have insulators at the 1' mark but as of now there is no wire placed at that height. Last year, the only rabbit sized varmint that caused any trouble was that skunk that dug up that chestnut. He also got 2 or 3 walnuts but unless something become a consistent pest, I like the idea of letting as much wildlife as possible move about unmolested.
The one thing I'll do differently if another opportunity arises is to put all insulators on the outside aspect of the 2 x 2s instead of just the hot wire being positioned so.
On a side note, everything was watered again today - one hour fifty minutes. We planted 25 more bringing the total up to 444.
