di ko binuksan yung unit,malay mo naka parallel lang yang mga output nyan sa input nya.kaso nagtataka ko para saan yung power supply di kaya sa light indicator lang yan,hehehe.kasi yung binili ko sa greenhills san juan na CATV amplifier na 1GHz ang maximum working frequency at mat output GAIN na 30dB ay may halagang Php7,500 yun sinisiguro ko na gumagana at totoo ang output na 30dB 100% tested.(yung sa satellite tv naman basta merong RF out yung receiver/decoder mo kasi ang output frequency ng KU band na disk papunta dun sa receiver/decoder ay 12GHz).

You can tell na lang via the actual signals sa TV, with and without. 

The 30db gain is a professional/commercial CATV amplifier for amplifying signals lost, specially use for bigger establishments or for village distributions.

Yup agree with you na as long as there is RF out on the decoders, you can have a multiple decoders connected.

'yung gamit naming Newstar merong 15dB gain per port (measured using Eight TV Signal Meter). nung binuksan ko, ang pagkakahiwalay nung dalawang port ay transformer type isolator, kaya kung 'di gagamitin 'yung ibang split, medyo mali ang termination.

gagawa ng sarili? simplest is 3 x 75 ohms delta connected.

Nakakatulong ba to improve RF leak cable signal ang amplifier/booster? suggestions?  nakakasagap kc tv namin. thanks

ibo-boost 'yung internet? kung malayong-malayo siguro kailangan, pero kung hindi lalagpas ng 50m siguro, walang effect masyado dahil nasa mababang frequency lang ang cable internet, frequency na hindi masyadong apektado ng cable loss ng coax.

yup ibo-boost sana yung signal ng cable internet.. ask ko lang diba nakakadag2 ng loss mga couple when it comes sa coax? hmmmm. so it won't affect much kung less than 50m . . .

'di ako familiar masyado sa cable internet, wala pa kasing cable net dito sa amin. ;D

kung properly terminated 'yung coupler at ok ang pagkakagawa, hati ang power sa split, bale -3dB per connection. maliit lang 'yung -3dB. though, kung 'yung mga typical na splitter, -6dB per split 'yun, pangit kung siya ang bungad.

kapag improperly terminated, malaki ang loss niyan. halimbawa 4-way coupler/splitter, tapos dalawa lang ang nakakabit, medyo may effect na 'yan. minsan pansin, minsan hindi. habang dumadami 'yung ganyang connection, lalong mas malaki ang effect.

meron din namang directional couplers para 'di bumabalik 'yung signal (mas common ata 'to noon nung common ang antenna). 'yan ang medyo malaki ang loss sa Tap. typically -10dB to -20dB.
