Indoor antennas can work. It depands on the details. Hopefully
the skylight looks to the south. BTW that thin sheet of plastic
that makes the skylight window will not protect from lightening.
It makes little difference.

It means those "plug-in" power suply boxes that plug into a wall
outlet and have a coaxial power plug. They are use to power cell
phone charges and notebook computers and you name it. Most
people have many of those around the hose. The output voltage will
be printed in the cube
(part 1)
This is a glass skylight window, not plastic.
Also, the skylight window in question is not the highest point on the
roof, there is a domed metal cover on an exhaust fan vent thingy...
Regardless though, landlord won't allow things to go on roof or in the
yard so I'm stuck with using the window.
Skylights work fairly well.. just stick the antenna on the bottom of the
window and hope for the best. If you have a handheld GPS (or phone
which does GPS), you can hold it up there and see if it works.
The worst case is that they've put some sort of metallic film on the
window to reduce thermal losses.. There are ways to fix that, but
non-trivial.
... Basically, this way I won't have to consider any waterproofing for
the antenna, and just hope that if lightning strikes it goes for the
exhaust vent dome thingy instead... Ah well whatever. My plan remains
unchanged in this regard --- it is going to be in one of the
south-facing (roof is angled) skylight windows.
And that's with a $6 navigation GPS thingy (USB puck-type NMEA-only)
That's navigation... Timing mode only needs "1 satellite lock" after
all, and I suspect I will at minimum be able to get needed "1
satellite lock" with nearly any active GPS antenna.
Ah, but this is Time-Nuts.. are you sure you don't need 1E-13
performance? You may not think you do today, but inevitably, the
horrible uncertainty in your time stamps will gnaw at your innermost
soul, and pretty soon, you'll be building choke rings, wrapping your $6
receiver in an oven, cobbling together some weird combination of surplus
parts.
