We don't know how much can be seen over the fence, so it's hard to comment on cosmetics.
I recently found a BUD lurking behind a 6'6" fence, but the upper
half of a white 8' solid dish was showing.
Kinda hard to miss.
Be Nice:
In your case, I'd have considered camouflage.
Maybe some paint along the top edge of the dish where it shows, to blend in?
Maybe a screen, fence topper, or tall bush to hide the upper part from view?
There are black nets to keep birds off fruit trees, which you could drape over it and some nearby trees.
Be Mean:
Since the 1 meter dishes are legal, and they can't stop those, you might tell them your alternative is to put up quite a number of 'em ... out FRONT!
See picture below - show it to them as a last resort.
... and tell 'em you are planning on running for the President of the HOA, next time!
Food for Thought:
You can take down the dish and lay it in the back yard and keep it around, if necessary.
If you're clever, maybe you can come up with a way to deploy it after dark.
Or, if a permanent structure has their panties in a wad, one way some members have fought back, is to put the dish on a trailer, so it's movable, and no longer a fixed structure.
SOL:
If you put the thing up knowing you were in violation of your HOA, I don't think you have a leg to stand on.
