Like Bill.Satellite said, H25 requires SWM. Your antenna is not compatible with SWM.
I use the D12-100.
If you would rather keep your H25, get a SWM8 and Power Inserter (PI). Run 2 coax cables from the antenna to 2 of the SWM8 line-in ports. Run a coax from a SWM8 line-out port to the PI. Run a coax from the PI to the receiver.
The D12 is easier, and only needs 1 coax from the antenna.
