Greetings

Lets see where do I start. I have been licenced since I was 16, in 1964.
My ham startion was located in the basement. My first antenna, a random
wire, ran from my antenna coupler, an L network, along the basement ceiling
out a hole drill in the frame of a basement window, up to, and over, the
eavestrough and down the backyard to the cloths line pole. About 75 feet.
Worked great on 80, 40, 20 meters.

Since then a pine tree located this on the house side of the pole has grown
to all but block my route to that pole.

Lots of time has gone by plus interests, etc, and I am planning a return to
hf, perferably cw.

My ham station has now moved from the basement, same house, to my old
bedroom facing the back of the house. My bedroom in now at the front side
of the house.

The most direct route to the back yard is now via a window. The window has
a permanent screen on the outside, it can be removed for changing, repair
etc. On the inside is a weather designed up and down sliding glass window.

My question is: is it possible to design something to allow me to pass a
transmission line, of any type, through a screen window, without
significantly effecting the characteristics of the transmission line and
without effecting the integrity of the screen window?
