I'd love to only have 2.5 dB loss. We're over 5 dB here on our 10 channel site but some of our freqs are 250 kHz apart too (800 MHz Trunked).
100W through the combiner and through 300 Ft of 1 5/8 cable (plus Polyphaser, jumpers, connectors, etc) yields between 15 and 20 watts (calculated) at the top of the tower.
