Hi

Mounting antennas outside a window can be impossible in some situations. If 
having the window “unlocked” is a security concern, you don’t do that.

If you have a window that is up and away from things, often a simple chunk of 
wood will do a pretty good job of propping it open, blocking the draft, and giving
you a structure to mount a small antenna. Some sort of flexible “foam” insulation
often rounds out the insulation / air blocking part of the combo. 

Cost wise ...not a lot. Durability might not be in the “last for years” category. For
a quick and dirty way to get things going, it’s worked for me a number of times
over the years.
