Only at Best BuyThis Insignia™ NS-HZ308 RF modulator converts line-level composite video/analog stereo audio signals to RF (coaxial), so you can easily connect your A/V devices to a TV without an A/V input jack.
This modulator works perfectly with my flat screen tv that has a broken coaxial adapter, we connected the coaxial cable to this and then the modulator to the tv. Perfect.
