While I understand your reasoning in most cases you would be being over cautious.
Re silicone grease, my understanding is that silicone should be totally avoided on electrical connections
If the existing route proves a no-go it may be worth checking the wall thickness below the window as sometimes croft houses have thin walls under windows even if the original inset has been framed flush with the walls to provide a deep cill. If there is a socket or other access it's worth a look, failing that you could make a very small hole in the plasterboard/ insulation and poke around with a coat hanger type wire to see if there is a significant void. Our croft house has about 600mm of stone in the main walls but only about 200 - 250mm below the windows.No, I think the coax was built in when the window was installed. It doesn’t follow a straight path.
Yes, I used it all over my boat and the connections kept like new. Use it all over car stuff now as well.I use on aerial connections, to pack limit switches, on crimps etc. Stuff stays like new.
I know what you mean. Our last croft-type house was as you describe, but I filled them in with studding, to make a decent-sized windowsill, anticipating it would used for storage of lots of crap, which it was, and a cat lookout point , which it also was.If the existing route proves a no-go it may be worth checking the wall thickness below the window as sometimes croft houses have thin walls under windows even if the original inset has been framed flush with the walls to provide a deep cill.

Nah, they just shifted it down a bit.but I had it in mind that the modern aerials were designed to reject mobile signals.
Unfortunately, it’s an old stone croft house, and the wall is 700mm thick. I’d rather not drill it if I don’t have to.
Out of interest, I asked about the wiggly track balun on Physics Forums. I find that several sources are often best when seeking an explanantion.RF can be "funny stuff" to work with. The printed circuit track between the two ends of the antenna could basically be a delay line, where the 180 degree out of phase signals at the two antenna terminals end up being in phase at the right hand antenna teminal in the middle image. The "ground" copper surrounds the "wiggly" track, and may help to perform some sort of impedance transformation. I suspect there were a good few prototype variations.
A Group B antenna would seem to be the one best suited to Rosemarkie's transmissions. Group K would be a 2nd choice.

Forget The Coax, Wire Up Your Antennas With Cat 6 Cable
These days, anything with copper in it is expensive. If you doubt that, a walk into any Home Depot electrical department, where the wire is locked up tighter than Fort Knox, will prove otherwise. C…hackaday.com
