for catv ba? use rf amplifier, bought one for around 600php. good for three TVs. may gain control pa. sa ace or handyman mayrun. sa raon malamng mayrun din yan at a lower price.
yup. it splits and amplifies the signal that a passive splitter degrades. it's a one in three out rf amplifier. but you have to plug it in, it consumes around 3 watts.
