Researching Microwave Reflective Coatings for Dish Antenna.


(2000)

Greetings,

I am looking for a cost effective method of applying a microwave reflective coating to a small parabolic dish.

Aluminum and Copper come to mind, but would require a protective coating to guard against oxidation.

I am aware of sputtering, and arc spraying, but again, protective coating would be needed, and equipment cost is very high.

Electroless nickel, I suppose would work, but haven't researched yet.

Any Ideas or comments would be very much appreciated.

Thanks!

What is your parabolic dish made of? If you can copper coat it, copper is not really reactive and you could maybe get away with spraying a lacquer coat on it, depending upon length of service. I don't know what quality your looking for, so this might be way too low for you - line your dish with aluminium foil?
