One good place to start looking would be at www.avagotech.com - I
believe that Avago Technologies is the current inheritor of the line
of RF Schottky diodes originally made by HP and then by Agilent. Some
of these parts are useful up to quite a few GHz.

I didn't see any UHF diodes on that site, did anybody else?

Click on "RFICs/Discretes" on the left. On the resulting page,
look in the "Product Tree" in the center, and click on "Schottky
Diodes".

The 5082-2800 series (glass-beaded) are specifically cited in their
data sheet as "particularly well suited for the UHF mixing needs of
the CATV marketplace".

In surface-mount, the HMPS-282x series are described as "RF/Microwave
mixer/detector diode", while the HSMS-282x "has been optimized for use
in RF applications, such as DC biased small signal detectors to 1.5
GHz, biased or unbiased large signal detectors to 4 GHz, mixers and
frequency multipliers to 6 GHz" according to the series data sheet.

I think that covers UHF pretty well, even if the web page and data
sheets don't use the specific term "UHF".
