problem with link 120 miles

I have a link of 75 miles from distance in functioning, with equipments OFDM conectorizados with dual antenna, the link in operation but the remote one goes out me and later that returns to ignite the pidu the antenna does not restart until it is done manually, 2 consultations: someone has a link as long as this one and if they have reference to the fault of which the pidu does not return to ignite the unit, already change wired up and pidu and the same thing continues spending(passing) this one fed on panels and batteries. Sorry for mi bad english.

Can you please elaborate it. Better send the diags to canopy support. Last time I had a weird problem I sent the diags to canopy and they diagnosed the fault was in my wiring.
