Seems it would not be difficult to manufacture an HF magnetic loop antenna to look like a satellite dish.  From what I've read these small magnetic loops can work very well.

Heck you could just tell people that your MFJ magnetic loop is a TV antenna.  How would they know any better?  And its not lying.  It could receive TV signals.

    How about a "satellite dish" that's made out of plastic, using the mast that holds it up as your antenna?  I heard of a ham who did this, but he used a fake regular "TV antenna" on the top.

   Could you pass it off as a roof exhaust fan?

Here is the funny thing...... I put it in a garbage bag, to help weatherize it and put it up on the roof...horizontally. I tied a rope around on of the vents and put it through the caring handle (it literally is the size of a box fan....along with a handle) and there it was....30ft off the ground. No one would know. It would still be up there had I not taken it down to put some inline ferrites on it. It began to snow and I didn't want to go back on the roof and have me come sliding down. It's slung against the fence waiting for the thaw.

I would expect you would really have to look hard for it.


As loops go (MFJ-1780), it's not as high Q is its brothers but it gets the job done. It does work better 20-30 feet off the ground, but it's sitting 6ft up slung against my wodden fence and it can compete with my 40m folded dipole 25ft up.

Here is the unit with a side taken off. It's depth is only about 4 inches and no one could tell what it was bundled in a dark garbage bag. Keeping the water out seems to be all it needs. We all know the winter we have and mine has not quit yet.
