Default 30 meter antenna solution

Hi I need a 30 meter antenna that is cheap and does not require guys. I also cannot have a wire dipole. My thought now is to use 2 30 meter mobile antennas and make a vertical dipole. I'm thing about using this mobile antenna:

Have you considered a delta loop? It is really cheap to build and can be fed with coaxial cable via a short matching section of 75 ohm cable. You can also hang it in a tree as needed. I have worked the world with this antenna.

A Delta loop is good except that I don't have the space for it or a good place to put it.

A pair of hamstick type antennas in a dipole configuration on 20m and up works ok but below 20m the efficiency is dreadful. I've tried them on 40m and they suck. A much better approach might be an end fed half wavelength of wire held up with a fiberglass mast and a 64:1 matching transformer at the bottom. That will work the same as a full size 30m vertical dipole but easier to deal with being fed at the end near the ground.

If you need to be stealthy, I think a mag loop is the best way to go. You can find plans on the net; but just to whet your appetite, here are 2 commercial manufacturers
