A piece of PVC through the wall with a dryer vent for a cover will work. So will a 45 degree elbow pointed down. The hole must be stuffed with something like fiberglass insulation to keep the critters out.

I think it is pretty sad when someone has to have a wife's permission to do something simple to their own home like running feedlines through the foundation - unless the wife is making at least 50 percent the house payments and paying at least 50 percent the bills. There are a lot of hen-pecked husbands in amateur radio.
