Q: What would happen if I attempted to run 2-antennas?

I am curious as to what the ramifications would be if I were to run two antennas off of one transmitter would me.
I currently have the Cybermax 15-20 xmtr. I have a Comet antenna as well as a dipole antenna. During my testing phase I've been alternating between both (which are at different heights and locations, measuring what signal strength I can obtain for different conditions for broadcast.
Then it occured to me, if I were to split the antenna output and run both antennas at the same time, what would happen?
I am no RF engineer, and with my very basic understanding of electronics, my guess is perhaps the transmitter may not have enough power to drive both antennas and a severe mismatch (swr) would occur, and if this in fact is the case .. the swr led should light up, and I would turn off the unit immediately, however- if the dipole (which is tuned to my selected frequency) and the Comet (which, to my understanding is capable of handling the signal- even with a 3db gain) are both in line, my question is would I possibly improve local (or even slight distance coverage)?? -OR- would there be some phase cancellation or other RF-induced issues which my lack of experience and understanding doesn't forsee?
Curious as to your thoughts or input on this.
