Hi Barry, Long time no here from.
EMCO sells two models: Model 4610 Royce Field Site Source works from 10Mhz - 600Mhz at a cost of around $2055 US. They make a better one Model 4630 "RefRad" Reference Radiator that works from 10Khz to 1 Ghz at a cost around $3895 US. The better model has a .1% frequency stability. It has a fiberoptic interface and comes with PC software for performing site attenuation, transmission loss measurements, and antenna calibration. The 4610 model we used when I worked at Zenith Data System. Worked good for site integrity checks. I haven't used the 4630 but am thinking about buying it this year for antenna calibration. These are the only models I am familiar with. If someone out there recommends a better unit, please let me know as well. Catch you later Barry, Brian Kunde LECO Corp.

Does anybody have related experience and knowledge about the product? Thank you very much in advance. Best Regards, Barry Ma 408/778-2000X4465
