Absolutely without problem. I have done both at once with no troubles.
Total power for 100% duty probably shouldn't exceed 100 watts at the
antenna (they are rated 200 watts max, but like I said, I have gotten
away with more. It all depends on how good the matching caps in the
base load are)

The antenna is indeed the Diamond X500, and at this point I have not had any
noice that I have detected thus far. Just need to make this setup work
until next spring when the tower will go up fo rthe repeater and the Decible
Products antenna's are in place and the beams for the remote receiver sites.
I was just not sure if the antenna can handle the transmit of both signals
at the same time.

I'll answer you honestly without flaming you :) If you use an antenna
such as the Diamond X700HNA (my preference in cheesy antennas), or the
Diamond X500HNA, they will both work well. You should take them apart
and SOLDER (I used silver solder) all the joints. I did this on my
X700HNA, and it works quite well. There is very little noise caused by
the antenna.. These two models seem to handle the power the best as
well. One of my UHF machines can put out 160 watts out of the duplexers
and it deals with it at high duty cycle.

I know what this question can lead to, and I know dual band
antenna's are not recommended for use on repeaters, but this is a
short term use, (Winter), need. Is there anyone that is using a
dual band atenna on their repeater system with a duplexer to split
the two bands. What I am attempting to do for the winter is use
this dual band antenna for both a 2 meter and a 440 repeater tied to
the same controller. The 440 repeater will then be receiving some
two meter remote bases. What will I expect to see with both
transmitters running at the same time, as well as the receiver
sensitivity. The 2 meter is running 78 watts from the duplexer and
the 440 is running 20 watts from the duplexer. Any thoughts on this?
