I'm trying to install a new antenna and need to connect to the "antenna in" port. The antenna has a standard threaded plug with a single center pin. This doesn't match the receptacle on the back of the unit! What do I do?

To connect a standard threaded antenna plug to the "antenna in" port on a Dynex DX-32L150A11, screw the threaded plug on the end of the antenna cable clockwise onto the "antenna in" port on the back of the TV until it is securely tightened.

Page 16: Working Principle Analysis Of The Unit
Working Principle Analysis of The Unit The analog and digital RF signal received by antenna will be sent to integrative tuner TUNER2(DA58GT-13-E, contains HF and IF amplifier circuits), which selects appropriate channel and sends the selected IF signal to the next level by the control of SDA, SCL. The analog RF signal sent to tuner, via high amplify and mixed frequency to get IF signal VIF, then it will be divided into two ways, one way will be sent to acoustic surface-wave ZF3 to IF filter and get better IF characteristics, then it will be sent to NF1(M61111FP) through pin20, 21 to do...
