Hi Mike,

You should try CYAN inc and the Z series. (US based) Very solid platform and very strong warranty.

Yes can do long distances without need to amplifier site (train tracks for example) but you need to make sure ground is 
stable and if using track bed of train track that the ballast is good and stable else ground tremors affect the signal 
quality.
