you have a massive back yard,i would but the antena up horizontal,and feed it with 450ohm ribbon and a length of coax,this will make it multiband from lowest freq up,you will also need a 4:1 balun,load of more info on the net for multibanding loop antennas.,wrapping stuff round fences is not a good idea,if you have kids or humans around.
Build a center fed dipole and feed it with open wire or ladder line. Either go into the back of the tuner with it, or connect it to a 1:1 current balun close to the house, and run a short low loss coax to your tuner. The way you have your antenna now is not efficient. It's like a side ways vertical with no ground radials. And fed with coax using it on a frequency other than where it's resonant, the line loss will be great and not much power will make it to the antenna.
A BalUn (coax to antenna transformer - coupler) is not as important with a receiver. All those COILS wrapped around the posts will have an effect. Zigzag the wire with bungies is much better, or go around the yard a couple of times, i.e. two or three loops, is better than those coils that act like a trap or choke. Ferrite beads on the coax at the antenna feedpoint is also a good simple BalUn, if the antenna is used for transmitting. Full wave folded dipoles and loops usually work very well.
@umajunkcollector Thanks! Ferrite beads is a great idea. I'm going to check the SWR across the entire 80 meter band and then try the 4 meter band as see what the SWR comes out to be. I was able to get 1.2 :1 so I hope it's not a fluke
@Lockemeister It won't work on 40 meter. It's only good for 80 meter band. that's Ok though, It's what I wanted. I make tuning adjustments with a MFJ Veersa tuner II.

@umajunkcollector i meant to say i want to try also the 40 meter band, not 4 meter band! I mainly want to use the 80 meter band though.
