yep. Just make sure they are not touchable.
I suspect that it is your power supply shutting down. I have had the same thing.
The counterpoise will help with that. chokes as well, but I would run the wire anyway.
Just run it around your baseboard, and maybe stuff the ends into a tennis ball or some such.
