I would have to dissagree with that. There would be more loss in the tx/rx by using a splitter than if you had two antennaes in proximity. You would get impedance missmatches causing high standing wave reflections (SWR). (gosh thats sounds really techie
Remember the phrase KISS : keep it simple stupid
Two antennaes on the A frame will interact, but this will be pretty insignificant, and give you a backup if one should give problems.
Dont struggle to make things easier!
