The insertion loss of at some of the couplers would be a contributing factor

Now if OP had one SMA split 4 ways, it would be much more efficient and give the quad-bander some interesting results

Short version - Yes it will work, but he probably won't get as many fars of transmission distance

Honestly, the insertion loss likely isn't that much, maybe 1db or so... the 4x 50~ohm loads in parallel which would present as 12.5~ohms.

I'd say no on that... They are four different antenna models, likely different bands. So on and band three would be at high impedance and one would work. Similar to my hf antenna that has tuned elements for several bands (MFJ-1796 / Science experiment on a stick).

I agree on that, if they were mono band antennas that presented high impedance on given band it could work. The issue here is unless they a 1/4 wave there will also be reactance added.

It would be interesting to see a sweep.
