I have a similar configuration. My dipole does interact with the tower.
I can see the tower's SWR rise and fall as I raise and lower the dipole on
Doesn't seem to matter at all. I've run it with and without the dipole and
the subjective performance is the same.
I just tune it out using the capacitor at the tower base and/or adjusting
the shunt wire.
Having the tower vertical is WAY worth it. The DX possibilities are a lot
better than I ever had with a horizontal wire.

I've got a 51' tower with a tribander at about 56'.? I've also got a
40/80/160 trap inv vee hanging at about 50' off the tower.? 40 works
reasonably well, 80 just ok and 160 pretty much not at all at that height.?
I'm thinking of shunt feeding the tower for 80 and 160.? Am I going to get
so much interaction between the loaded tower and the 80/160 dipole that its
really not worth doing?? Or... since their vertical and horizontal polarized
will the interaction not be much of an issue??
