It's erected for the reception (6)
I believe the answer is:
aerial
'it's erected' is the definition.
(communications device erected on top of a house)
I cannot understand how the rest of the clue works.
(Other definitions for aerial that I've seen before include "Antenna for attracting signals" , "Radio waves receiver" , "Device for radio transmissions" , "What may receive" , "Rod for receiving radio waves" .)
