Sounds like a similar set up that I have. Mine is terminated at 2 ends, where it meets the pasture fence. My Donkey keeps them out of the pasture. I have an entry way, with T-posts set approx. 42" apart, and use the spring loaded gate handles, connecting the fence. I made another entry way approx. 14' wide with the same set up to get my tractor through, to plow and disk. My top wire is at about 5' high, and for the most part kept Deer out, except, occasionally one pesky Doe. I read in a garden group, to late to try it last year, putting some peanut butter on some wires, since Deer apparently like it, they will lick it and get shocked. As mentioned above, it will startle them, but not harm them. I plan to try that here in the next couple of weeks before anything starts to grow.
Something that also worked great, I did several years back, was to plant a hedge fence of Sunflowers around the perimeter. I planted 8 rows of the tall striped type, and 4 rows of the short black oilers, within a 36" width. The theory is, Deer will not jump over something, they cannot see the other side of. Planting the shorter black oilers, fills in the lower midsection of the tall stripers, making a lush hedge fence. They may browse on a few when small, but there are so many, it made little difference. It worked great for me, until several years ago, when we got a lot of Spring rains, and drowned out part of them in the lower part of the garden, and allowed an entry for the Deer. I plan to do the same this year, and still have the electric fence. I also planted Marigolds along the part that's right at the road, approx. 4' from the electric fence. Deer don't like the scent, and will stay away from them. I plan to do another side this year, where "she" seem to come in.
Sunflower seeds aren't all that expensive if you buy the 2 lb. bags, to feed to the birds. That sized bag will plant a border around mine, enough for 2 years. After that, the germination rate gets poor. I just put the rest in the feeder for the Cardinals, so they don't go to waste.
Here's a pic from 2015, where I planted a hedge fence around the Sweet Corn. Worked great, until that old heifer got a taste for the Heirloom Mortgage Lifter tomatoes... She would eat those when ripe, yet, pull the Celebrity hybrids off, and drop them on the ground. Hoof prints in the dirt, and teeth marks in the tomatoes gave her away.
