On a side note.... Mikrotik 4 port NIC cards are designed to work up to 450 ft, 
based on the Data pairs. POE distance can be resolved by uping the PS voltage a 
bit, or using 48V. 
My point is, if you use a Router on the ground with the Mikrotik Nicks, its 
feasible to put Radios at 400ft at 100base-T.
We had experimented in the past with using two CAT5s one for data and one for 
Power, and then combining at the top of tower. That did not work as well, 
because we had issues with the cable combiners getting messed up by either gel 
running down into them or getting corroded by elements. (we had the couplers 
inside a nice plastic-like case, the ones sold by hyperlinkltech and LCOM, but 
they still got corroded.  We did better with one long run of CAT5 without any 
breaks in it.  It should be noted that POE voltage over long distances can 
cause degregation to data pairs which one reason POE is spec'ed at 300ft. But, 
it had worked for us at 425ft.

My point here is that if you have CAT5 breaks up at the top of the tower, make 
sure you go overkill on prep to prevent corrosion. Make sure you got silver to 
solver connectors or gold to gold connectors, not silver to gold that will 
oxidide. Dont jsut go enclosure, but go NEMA.

Bob's suggestion of Coax up the tower, sounds safer though. 

Bob, do you have any suggestions on GOOD EOC brands? 
I was thinking of doing it that way on an upcoming project.
Sure I could google it, but with a new product up a tower at 500ft, I'd prefer 
a trusted recommendation.

  You could do 400' IF you lock it down at 10Mbps. But then, what would be the 
point :)

    Bob that's a great idea, the second one.  I don't recommend a 400' cat5 run

    At 400' the CAT5 would probably work fine.

    Another option would be bias T's and Ethernet over Coax converters.
    Then just run a piece of LMR400 or even RG6 up the tower and you are
    ready to go. Use siamese (dual) RG6 and run power on one and Ethernet
    over coax on the other.  Pretty straight forward. EoC converters are cheap.
