Hello Everybody!!!!!!!!!!!!

I have two antennas that I would like to mount on my roof 1 homemade jpole and a 17.5 vertical?????
Is it possible to use the two antennas and switch back and forth. I also have 2 radios President hr2510 and a Grant xl that I would like to be able to switch back and forth. There should be a way to do this without having to run 2 coaxial lines , at least I hope there is. I hope this is not dumb idea as I am new to this hobby and need a push in the right direction.
Hope to hear from someone \ anyone soon
Thanks
