Terk passive inline signal amplifier BIA-20 doesn't work

04-09-2005, 05:40 PM
I've got a Terk inline signal amplifier (powerless) and when I use it either to feed the OTA to more TVs or OTA+RF modulated satellite signal on 1 coax, the amplifier does worse than good; the image goes bad, bad. I tried simply from OTA antenna just to one TV and same thing. The instructions says that accepts input from Roof Antenna/Satellite/CATV and output to TV, VCR, SAT. receiver or Cable Box. Am I doing something wrong or this is defective? Thank you.

Most inline amps require power from either a satellite receiver or a power injector down at the TV end. What is the model number?

It is a Terk BIA-20.

Here is what they say in info pdf file:

If the amplifer is being used in a system that contains only an off-air antenna then, the amplifer should be placed near the antenna.

Line powered amplification: The BIA-20 amplifier is designed to boost weak satellite dish and terrestrial antenna TV signals being fed into a DBS satellite receiver. The amplifier is powered directly by voltage from a DBS receiver, so an extra power supply is not needed.

If you are trying to use this amplifier without connecting it to a receiver that supplies +13v to +18v then you will need a power injector. Terk's power injector like they supply with the TV55 antenna will supply +15v to the amplifier. I would suggest you contact Terk directly to get the power injector as I don't think retail stores sell it separately. See: http://www.terk.com/support.html
