I have need of a directional antenna for a 30 foot path within the house.
(the microwave oven wipes out the signal).

Yikes! I have never seen that. I would be concerned about leakage.
Sometimes I have torn into things and found stupid stuff like paint over
grounding surfaces or rust in the compartment. There is a critical ground
around the probe entrance.


The laptop computer is downstairs about 10 feet from the microwave, and the
wireless router is upstairs about 30 feet away with a desktop(and the path
goes through three walls and the floor. The microwave doesn't wipe out the
laptop, but slows things down a bit. A directional antenna would solve the
problem. I'm not trying to increase range at all.
