[Elecraft] OT: Stealth Indoor Antenna Questions

[Jeff]

Hi gang,

I'm going to install an indoor antenna to be fed by my K2, and I'm
considering using this 30-gauge wire for it: http://tinyurl.com/yjjcen  This
wire would be great aesthetically, because it has white insulation to match
my walls and ceiling.  The main question is, Can I get away with running my
K2 at 15 watts into such a miniscule gauge of wire?  30-gauge is awfully
tiny.  Should I limit my power to 5 watts at all times (which I would hate
to have to do, since I've found that the extra 4.5 dB sometimes makes all
the difference)?  Or do I need a bit thicker wire, even if running only 5
watts?  Each leg of this bent-to-fit antenna will be about a quarter
wavelength on 80 meters, and I'll be using it on all bands with the KAT2
tuner.

Does anyone know where I can buy a slightly thicker gauge wire, such as
26-gauge, that has white or off-white insulation?

One more question:  I plan to run the wire along the line where the wall and
ceiling meet.  What inconspicuous means would you use to hold the wire in
place?  I'm thinking of white thumb tacks or clear push pins.  I'm afraid
that anything sticky, such as Scotch tape, will come unstuck, requiring me
to borrow an extension ladder to re-stick it, as I have a "cathedral"
ceiling, which is way up there.

Thanks very much in advance for any advice.  Most of the antenna will be up
27 or 28 feet, by virtue of being on the third floor, so I'm hopeful that it
will work pretty well, at least in comparison with most indoor antennas.

Thanks again, 73 & 72,
