    Another mathcad alternative

    I think until someone puts out a product that supports units, MathCad will be safe in maintaining it's market share on this type of software tool. Should one of these groups ever figure out that units is a key component....MathCad will see some real competition.

    Inductive Power Coupling

    Thanks to all, so much for IEEE's new website. I did several searches on Explorer and Don's paper did not come up. I just reran the searches with Don's title and his paper came up as well as some Grant Covic papers. That is enough to get me going in a direction. We had figured that the...

    Radome for 2.4G & 5.8G Radio Antennas

    Thanks for the info. Yes, this is an ISM type application. We are pushing the envelope on range. Trying to squeeze out as much performance as we can. Pushing the antenna height as high as we can get, using directional antennas, keeping coax lengths as short as possible, etc. Regards Larry

    Radome for 2.4G & 5.8G Radio Antennas

    We are trying to find out a good material to use that is RF transparent (relatively). We are trying to house the antennas out of the elements so we don't have to worry about salt spray, icing, etc that a marine environment presents. Any thoughts or ideas on where to look would help. So far...
