I have a UHF repeater on a 40+ story building. While not solid, it is
HT-accessible from the bottom sub-basement, 4 stories below ground
level. Antenna is a GP9 only; no radiax.
My guess is that the signal is rattling around between buildings (there are
several highrises around it that are the same height & a couple that are
taller) & bouncing back in from the outside.
If it's an option, consider locating your repeater to an adjacent building
& directing the RF into your building from the side rather than the top.
