- ARA1-15EQ/AC – No reverse gain but it has equalization – likely we only need gain down at Claudio's house and not Luizom's.

HDA-1000 Amplifer – has 30 db of gain with slope / gain control and a passive return.

Parts List
· Qty=3 amps. HCDA-1FRA 1 for spare or if you need more gain. ( each comes with Pwr supply I think ). If not get the pwr supply separately. VERIFY!
· Qty= 2 POE just in case you need to run from Claudios and from your house. Most likely you will end up with a spare.
· The cable you can find on ML: http://lista.mercadolivre.com.br/rge-06
