All the numbers you quoted are on the high side. For a 300' tower you would use a large diameter (1-5/8") cable to connect the antennas to the base station. This cable costs about $10-12 per foot, plus installation and connectors.

Good receive filters that I know have been installed in at least 1000 urban cell sites for 800 MHz cellular cost about $2000 each. You need 1 for each receive antenna. For rural sites with their requisite less stringent filtering needs, a $500 filter has been used extensively with good results. I have also seen sites where no additional filtering was used outside of what was provided with the OEM equipment. If you are duplexing a transmit and receive path onto an antenna to save the cost of an antenna and the feedline, the duplexer provides sufficient receive filtering for some applications. People don't buy what they dont need, provided they are smart enough to know it.

Transmit amplifiers costs are all over the board depending on if it's a single carrier or multi-carrier amp, and what the power level is. But the most I have seen a multicarrier, high power PA cost is around $30K for cellular. PCS amp's would be somewhat higher but only about 10-20%.

So all the numbers you have been quoted are quite high, suspiciously I might add, to pump up somebody's story about their product I suspect.
