I have radar dish that I bought years ago at a hamfest and used it as a parabolic mic. However I would like to sell it as I no longer have a use for it. It seems to be made of some type of fiberglass and very light in weight. The seller told me that I was taken out of a military aircraft.
So my question is can a dish like this be used on most of the ham microwave bands or is a special size required for each band?
To see a photo got to http://www.flickr.com/photos/10025089@N05/
. The ruler in the photo is 12 inches across. The dish is 24 inches across and it is about 9 inches from the bottom of the dish to the feed point.
