Topband: Antenna Question

[Jim Murray]

Hello All!
The good news from here in the Adirondack Mountains is that we now own a place in a warmer climate to spend the winters in.  The bad news is I will miss a lot of the best 160M conditions AND I have a no outside antenna deed restriction.  I don't know if I can possibly hide at least a vertical there or not.  Recently I've seen a couple of articles regarding "invisible antennas", using smaller wire etc.  I want to at least get a 20M dipole up somehow.  Aside from any possible ideas on antennas I am wondering about the efficiency loss of using small diameter wire (100W).  I  have a roll of #26 I'd be willing to blacken and try it out but will it work as good as 14 or 12?  I don't have a balanced line tuner and would feed the ant. in the center with a balun (hard to hide those).  I have one tree in the rear of the home which looks to be about enough distance for only a 10-20M antenna.  The tree could possibly hide a vertical of about 25'.  I
 don't see any other options right now and lowbands will surely be restricted up to the time the xyl decides it's time to head South.
Regards to all,
